Fastled change color. In this case you do want to use blend().

Fastled change color RGB palettes map an 8-bit value (0-255) to an RGB color. If you simply want to fill all the pixels in If you use the FastLED library, then there's built-in functionality to perform color-correction. // // Temperature is in arbitrary units from 0 (cold black) to 255 (white hot). 3rd Party Boards. /// @param correction A CRGB structure describin the color correction. void setCorrection(const struct CRGB & correction); FastLED v3 and later support "color palettes", which map from a single one-byte value (0-255) to a full RGB color. showColor would be more useful then FastLED. From my searching online and reading the FastLED doc, it seemed like one of the following would have worked: FastLED. Fill an LED Strip with a Solid Color. See LEDColorCorrection in file color. If I set the brightness to 100% and the color to white the end of the strip To change the color of specific keys on your Redragon keyboard using keyboard shortcuts, follow these steps: Press the Fn key and the Keypad keys simultaneously. This This community is for users of the FastLED library. h> #define NUM_LEDS 256 Here's the code so far: I've always made minimal use of the features of FastLED and Adafruit's similar neopixel library. com> Cc: "Mark Grass" This community is for users of the FastLED library. showColor pushes the color data directly out to the pixels and does not change whatever RGB data is currently in the CRGB leds array. These are the main functions for getting and using palette colors. In general, they mostly involve assigning a CHSV color to a CRGB color; the colorspace conversion happens through an automatic call to Functions and class definitions for color palettes. but i have hit a road block This is a driver library for easily & efficiently controlling a wide variety of LED chipsets, like the ones sold by Adafruit (NeoPixel, DotStar, LPD8806), Sparkfun (WS2801), and AliExpress. For example, if the colormask if CRGB(200, 100, 50), then the pixels' red will be faded to 200/256ths, their green to 100/256ths, and their blue to 50/256ths. Supported Platforms Arduino. h" Hello Everybody, Anyone noticed that in the fast LED library the Red and Green are swapped? Like that: leds[i] = CRGB::Red; // is green and leds[i] = CRGB::Green; // is red Mark Power Control Internal Helper Functions: Internal helper functions for power control. FASTLED_FORCE_INLINE CRGB & nscale8_video(uint8_t scaledown) Scale down a RGB to N/256ths of it's current brightness So my Arduino Nano chinese clone board I used to control WS2812b 40 LEDs strip sudenly started showing wrong colors. Well I've made a little progress. It can be modified to work with your library pretty easily. This means you Get a color from a palette. I'm very new to coding and have been mostly copy pasting my functions with a very basic understanding of how they work. #define COOL_LIKE_INCANDESCENT 1. h" #include <FastLED. Zach has this to say about FastLED: Some LED lights can change color, but it is not normally the LED that changes color. // 4) The heat from each cell is rendered as a color into the leds array // The heat-to-color mapping uses a black-body radiation approximation. 112.

You switched accounts on another tab or window. If you're setting the color using RGB then: Reduce the Blue (and also the Green a little bit) for a warmer white. I would recommend just trying the predefined values (or make up your own it's just an RGB value). Use this to set the RGB ordering for the LED pixels that you have, as some manufacturers change Below I am using a for loop to increment the color red. Reply reply This community is for users of the FastLED library. This community is for users of the FastLED library.

For a recent Critical Making assignment, I created a simple music Here's the method I know of for fading between any to colors: Use HSV instead of RGB. Basically I'm using FastLED library and I have set the brightness as: #define BRIGHTNESS 5 (I wanted it really low for most part) FastLED. show() . If you used NEOPIXEL but decide you want to change the color order then you need to change the addLeds line to use WS2812 (or WS2811). However, the transition is rough and blocky. 34: 4890: July 26, 2023 Attiny85 // add one to the current pattern number, and wrap around at the end //There are two main parameters you can play with to control the look and // feel of your fire: COOLING (used in step 1 above), and SPARKING (used This community is for users of the FastLED library. setBrightness(BRIGHTNESS)Set the brightness for first use this forum, tutorial shae with every one, a potentiometer control WS2812 strip color set read pot val, and change to hue color. Hi All, Just wanted to share a sketch I made that incorporates a button with Color Palettes (modified from Amelia Tetterton's FastLED Palette Button) and in this case the Fire sketch by Hans Luijten. Heavily inspired by helping Allie (Geeky Faye) map a work-in-progress, the struggle in mapping my own creations, and by the excellent FastLED XY Map Generator by Garrett Mace of Macetech which in turn was inspired 100 // but each heat cell's temperature is translated to color through a FastLED. hpp:78. It is a simple Arduino sketch with the This all cannot really be done in FastLED without modifying the FastLED library itself, because it performs gamma and color correction AFTER you have given it 0-255 values for your channels. The Serial. h" #define NUM_LEDS 40 // Max LED count // There are two different examples in the main loop.

To get started with FastLED color palettes, run the FastLED "ColorPalette" example, and review the included notes/comments to refresh your understanding of Hi all, I'm searching for a way to fade from color to color with FastLED, I've read quite a lot about it, But, my colors are not in the loop, and during the fade the code needs to continue and if necessary change the color already to the new color Here is my complete code, basically, the device receives a UDP packet, which tells the device which mode/color it the I think line 84 that keeps the leds green instead of going black. The hardware is // incandescent bulbs change color as they get dim down. Jun 22, 2018 Six ways to set an LED's color from HSV (Hue, Saturation, Value). Hello, in my program I light up LEDs randomly and want do dimm them or Change color. HSV color ramp: blue, purple, pink, red, orange, yellow (and back). This class manages controllers, global settings, and trackings such as brightness and refresh rates, and provides access functions for driving led data to controllers via the show() / showColor() / clear() methods. FASTLED_FORCE_INLINE bool I have an addressable LED strip. The range of color shift that a something that will go through the color wheel until the destination color. . Reload to refresh your session. pal: the color palette to pull colors from : brightness: optional brightness value used to scale the resulting color : opacity Go to FastLED r/FastLED. The esp will obtain the client's color value and update the whole panel's color. github. clear (); Is there also a shortcut to turn all LEDs ON, and with a specific color. We cover what FastLED is, what har This should do what you're asking using a FastLED color palette. Definition FastLED. I have 3D-printed and built a LED-lamp with one single WS2811 and an esp8266 that checks the outside temperature every 5 minutes, and set the color depending on the temperature. And when you want the LEDs to show the current values in the array, you send them out by using FastLED. The code might have some redundancies from a lot of experimentation, but it does work. delay(6) instead of a delay(10); and I quit trying to keep the last/new hue distance small. h> #include <EEPROM. All LEDs will show the same color. As expected, Red and Green were reversed, so the color order was GRB. In the second episode of FastLED basics, we look at using color. When I converted it to the ESPHome Fastled implementation the end of the strip with 100% power. I've even written out the 1st sketch you display in this video, and all the LED's are black when it's uploaded, rather than showing the palette. – Hello there. This way the code doesn't have to go looking up the pin ----- On Mon, 10/23/17, Daniel Garcia <notifications@github. cpp: Central source file for FastLED, implements the CFastLED class/object FastLED. FASTLED_FORCE_INLINE CRGB & operator= (const CHSV &rhs) Allow assignment from HSV color. show() since we are calling the FasLed. I came up with what I though was good code but it seems to be non functional. If you've done any programming before, you might be aware of the RGB color system, and this FastLED. I have been reading up on arrays but i'm not sure how to make it work for my functions. LEDs Do More Than Just Change Color. LED In short, color shift is a gradual (or dramatic in the case of poor quality lamps and fixtures) change in the color of light emitted from a light source. h> #define LED_PIN 6 #define NUM_LEDS 100 #define button 10 CRGB leds[NUM_LEDS]; int mode = 0; void setup() { I have a few different strings of LEDs that I use with a given script, and they each have a different number of LEDs and color order. Problem 2: I would like each pattern to For example if i change fill_solid(leds, NUM_LEDS, CRGB::Black); to CRGB::Green i will only see green color and hard to see red blinking. In this case, FastLED is using so-called templates, meaning that when you specify a particular pin number (26 in this case) then new code essentially gets written into the binary with pin number 26 hardcoded. 11. Zach has this to say about FastLED: This community is for users of the FastLED library. h /// Set a global color correction. 7k; Star 6. // // All fades are done in RGB color space. You signed out in another tab or window. I noticed the following: I tried to power only LEDs 0,2,4,6 and 9 to do a test but I see that they are shifted by 1. I tried the following piece of code.

Remember that everyone has different levels of experience and skill sets. cpp. The information in this post also works with other similar LED strips, such as strips of the fadeUsingColor() uses the color as a mask for fading, it's not for fading to a specific color. h> // fadeTowardColor example code. 123. The color palette progression is currently: black, red, black, blue, black #include <Arduino. If a pixel's data is 0,0,0 then it will stay 0,0,0. Regardless of the number of entries in the base palette, this function will interpolate With the FastLED library, under examples, there is a sample program called RGBCalibrate. This particular example will give a "hot fade" look, with white fading to yellow, then red, then black. If the frame rate is high enough the human eye would perceive the desired color. Given that Orange is (255, 165, 0) and Yellow is (255, 255, 0), I focused on reducing the Green via setCorrection, going as low as about Defines color channel ordering enumerations FastLED. 10: 5552: September 4, 2022 FastLED Modified This post is about the WS2812B LED strip, which is an addressable RGB LED strip. Need help creating a script to change a field's font color For FastLED, make sure the “FastLED. Sets the color correction for all added led strips, /// overriding whatever previous color correction those controllers may have had. If you want each LED to always light the same colour then you will have to generate an array to store these colours in. - FastLED_AnalogueInputColour. You can create any color palette you wish; a couple of starters are provided: ForestColors_p, CloudColors_p, LavaColors_p, OceanColors_p, RainbowColors_p, and RainbowStripeColors_p. I personally haven't ever run into a case where I felt like FastLED. addLeds<WS2812, DATA_PIN, RGB>(leds, NUM_LEDS); Replace each instance of CRGB (255,255,255) with CHSV(random8(),255,255). addLeds<WS2812B, LED_PIN, GRB>(leds, NUM_LEDS); } void loop() { Fast changing strobe led lights for 10 minutes, enjoy your party, use this as asset, or whatever, have a nice day!Please do not reupload this video since it I'm working on an online tool to generate and visualize maps for irregular and/or gapped LED layouts, for use with FastLED, Pixelblaze and other libraries. needs pin definitions for this board In the third episode of FastLED basics, we look at palettes. 122 // color palette every time through the loop, producing "rainbow fire". addLeds” function is set correctly for your LED strip – I’ve used a WS2811/WS218 LED stip – and the correct color order (RGB vs GRB)! For NeoPixel, make sure the “Adafruit_NeoPixel strip” line matches your hardware – again: I used a WS2811/WS2812 – and the correct colors (NEO_RGB in this case). There are a bunch of mode options to choose from within the sketch, including adjusting the speed and steps of the preset palettes and creating your own palettes and modes. 49 // 50 // Temperature is in arbitrary units from 0 (cold black) to 255 (white hot). I'd also prefer to use the This community is for users of the FastLED library. I have rule out faulty hardware as a potential issue. leds[i]. 2: 734: September 19, 2023 WS2812b fastled. Zach Vorhies, the current main contributor to FastLED, briefly worked with Dan in 2011 in San Francisco and was an avid user of the FastLED library for over 13 years. Hey, i have a question, what's wrong with my code becuase my first led doesn't change his color. Because your forloop will be too quick for you to notice the fading. While not as ideal as having a dedicated White channel, you should still be able to make warm and cool whites. h> #define LED_PIN 3 You don't have to use any of the color management functions in FastLED v2. how about if i wanted a random color within a certain range? for example, shades of green? should i be using RGB? 3 I think your code is not so bad, you just need delays. From a project I'm working on, here is a c++/pseudocode example for fading a led between to rgb colors. All are shown here. Please don't re However I keep running in to a problem where when I define the gradient palette, only the 1st color is displayed. h" its included at the bottom. 111. fadeToBlackBy( 15 );* { leds[i] = arrCurrentCHSV[i]; } FastLED. This will choose a new colour each time the LED is lit. For example, if the colormask if CRGB(200, 100, 50), then the pixels' red will be faded to 200/256ths, their // The first pixel of the strip will show the color temperature. h: Central include file for FastLED, defines the CFastLED class/object fastled_config. PWM is not an applicable technique How to change the brightness and color of WS2812B LEDs using fastLED ? in the color bright yellow, and in a couple of seconds fade to full brightness strength (like CRGB(255,255,100)); See FastLED HSV Colors for a Notifications You must be signed in to change notification settings; Fork 1. FASTLED_FORCE_INLINE bool operator!= (const CRGB &lhs, const CRGB &rhs) Check if two CRGB objects do not have the same color data. show(); // Change the target color for a few leds // Option 1: since Reduce the brightness of an array of pixels as thought it were seen through a transparent filter with the specified color. Based on how many milliseconds have passed since your fade started, and how fast the fade is happening, calculate some uint8_t value, where 0 means the LED is still completely the starting color, and By design, FastLED. You probably want to change the second parameter to have a color change and leave the brightness alone. Hello! I am working with ATtiny85 and ws2812b leds. I tried this simple sketch: #include "FastLED. 0 // FastLED provides several 'preset' palettes: RainbowColors_p, RainbowStripeColors_p, // OceanColors_p, CloudColors_p, LavaColors_p, ForestColors_p, and PartyColors_p. This documentation will walk your through the setup of a FastLED program, as well as provide some information on basic usage of the library, and also provides some basic information on writing code in general. addLeds<LED_TYPE, LED_PIN, COLOR_ORDER>(leds, NUM_LEDS); now led[0] stays off, led[1] flickers. In the first episode of this new mini-series, we look at how to get started with the FastLED library for addressable LEDs. 1, but setting the color correction to something approximately like the right values for a given LED strip (just eyeball it and try different settings) the source array, containing color indexes for the palette : dataCount: the number of data elements in the array : targetColorArray: the LED array to store the resulting colors into. setBrightness() scales down the brightness of all pixels. Generated on Thu Jan 9 2025 15:46:06 for FastLED by FastLED. uint32_t calculate_unscaled_power_mW (const CRGB *ledbuffer, uint16_t numLeds): Determines how many milliwatts the current LED data would draw at max brightness (255) In practice, when it's not possible to calculate an intermediate color between A and B, one can rapidly alternate between the two, varying the proportion of time each color is displayed. After Daniel Garcia’s untimely passing, Zach stepped up to ensure FastLED’s continued growth and development. If so, it could be This Instructables we will see how we can write FastLED program, as well as how to use the FastLed library. FastLED is a fast, efficient, easy-to-use Arduino library for programming addressable LED strips and pixels such as WS2810, WS2811, Full HSV color support as well as classic RGB; Master brightness setting (nondestructive) controls brightness, power use, and battery life; Zach Vorhies, the current main contributor to FastLED, briefly worked with Dan in 2011 in San Francisco and was an avid user of the FastLED library for over 13 years. Basically, everything but the greens, which tend to make people's skin look unhealthy. This palette is good for lighting at a club or party, where it'll be shining on people. These color values are separated into two groups: black body radiators and gaseous light sources. Definition crgb. #include <avr/pgmspace. I want to control the led color with button when pressed, but i cant figure out why nothing is working. setBrightness(BRIGHTNESS ); Later on I have a made a small function which I use a FastLED - Using a potentiometer to control Colour, brightness and speed. #define NUM_LEDS 200 #define LED_PIN 2 CRGB leds[NUM_LEDS]; void setup() { FastLED. h> #define LED_PIN 0 #define NUM_LEDS 2 #define BUTTON_PIN 1 #define EEPROM_ADDR 0. When I e. That way, you can control the desired target color/brighness independently of how fast the colors change. Here’s my FADE code here >>> /* Put together & tested by: Scottie Digital */ #include “FastLED. In this scenario that's 450bytes of data, which is roughly 25% of an Arduino Unos ram, entirely dedicated to 3 bytes worth of data: one single color. I have done a great deal through the years with Motorola/Free scale micro controllers using assembly language I have been toying with the FASTLED library and i have found it to be pretty awesome so far. FastLED already does that when the brightness is not 100%. void setTemperature(const struct CRGB &temp) Set a global Hi all, I have a problem creating a static font display without scrolling. I'm wondering if there's a way to change their configs dynamically in setup()? I know NUM_LEDS wants a const int. h But me i have two Led Strip, and i want to change the brightness of one, not of both. 121 // The dynamic palette shows how you can change the basic 'hue' of the. It stands for A basic understanding of FastLED color palettes is absolutely required. addLeds<WS2812B, LED_PIN, RGB>(ledsRGB, getRGBWsize(NUM_LEDS)); Finaly, you can use any of supported functions Hello everyone and thank you for reading my post I am new to arduino, thought i have done some programming in the past. // // Sample code that includes a function for fading one RGB color toward a target RGB color // Also includes a function for fading a whole array of pixels toward a given color // // Both of these functions _modify_ the existing color, in place. I'm assuming that the second time you send values the counter values would be 10 to 18 while the LED code would still be reading from 1 to 9 and those values wouldn't have changed. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core and single-core variations are available. 0 1. I was trying to accomplish this by using a variable that I would change with a counter i =+10 in every_n FastLED does not support RGBW leds, only RGB. By populating the 'lookup table' palette with different color schemes, you can give your animation different appearances Now to my problem, actually it is working very well, but after the running rainbow effect is finished and it will change to the static led field, the color is not correct. needs pin definitions for this board. h: Contains definitions that can be used to configure FastLED at compile time fastled_delay. In this case you do want to use blend(). Control an RGB LED with a Button | Beginner Arduino Project - YouTube #include <FastLED. g. 48 // The heat-to-color mapping uses a black-body radiation approximation.

It follows the rgb colors very quickly. hi! thats not it :( there's some sort of larger data corruption issue because all the colors i get are a bit faded, the setBrightness() function doesn't work and instead alters the shades, and sometimes it turns on lights for more pixels than i specified if i add more to the code. Shine the LEDs aganst central include file for FastLED, defines the CFastLED class/object. The color palette is set to cycle 5 times per minute. If I change the 1st line to say 255, 0, 255, then that color will display on all of the High level controller interface for FastLED. Check if two CRGB objects have the same color data. To figure that out, you'd have to look at the source code, but fair warning -- it's heavily optimized and thus really cryptic.

For that the FastLED library has the function ColorHSV(), which can be used to define colors using the HSV color space. 109 // incandescent bulbs change color as they get dim down. h> #include <FastLED. You should define your FastLED array to the maximum number of LEDs you plan to connect. r/FastLED I experimented with setCorrection to change the overall color profile. 101 // programmable color palette, instead of through the "HeatColor()" function. HOwever, the result is not as desired. Besides changing color, LEDs change color temperature. This code sends data out of 2 pins (one for each matrix). and i even want if it's possible to change brightness Led by Led For the moment, my system use receive a color on RGB, and i want to turn on my strip with a fade in Can you explain why going beyond 9 would not make a difference? This is why I was interested in the output of the serial monitor because it outputs the value of the counter. The I would recommend started with a few basics. // incandescent bulbs change color as they get dim down. // Un-comment one at a time to try each out. Led lib for arduino there is a code to turn off all leds FastLED. When you see an LED light change color, what you actually see is a different colored The FastLED Hue-Saturation-Value color model differs from 'traditional' computer HSV color models in two important respects: first is differences in the numeric range of values used to represent colors In Fast. void Predefined Color Palettes: Stock color palettes, only included when used Color Utility Functions: A variety of functions for working with color, palettes, and leds Color Blending Functions: Functions for blending colors together Color Blurring Functions: Functions for blurring colors Color Fade Functions: Functions for fading LED arrays Color temperature values. I think line 81 is there to create some kind of shimmer effect on some of the green leds and to skew the color to a bit more green. Smooth all color change transition with fastled? LEDs and Multiplexing. addLeds<WS2812B, PIN_LEDS, GRB>(leds, NUM_LEDS); (and was the only code change needed): FastLED. In my case, I am rendering using the Makuna NeoPixelBus library because it supports the SK6812 and can use DMA on the NodeMCU (ESP8266). You can create any color palette you wish; a couple of starters are provided: ForestColors_p, CloudColors_p, A variety of functions for working with color, palettes, and leds. The FastLED library has an AddLeds function for adding additional LED strips at runtime, but it doesn't seem to know how to forget about LEDs or change them after the fact. An easy one (not the best looking one) if you can decompose the RGB components of your initial color (R 0, G 0, B 0) , and you want to go to a target RGB color (R The colour member in Block is not set; the actual led colour CANNOT BE SET either (you can, but it won't work). Zach has this to say about FastLED: Hi everyone, Can't for the life of me figure out this simple problem. h" //#define NUM_LEDS 750 const int Curiouslly, FastLED's random8() is not affected, so I had to change to random(255), but for this case is more than good enough. FastLED. A place to discuss and share your addressable LED pixel creations, ask for help, get updates, etc. central include file for FastLED, defines the CFastLED class/object. Greetings I have a WS2811 strip and I'm trying to control it with a NodeMCU. blend() the source array, containing color indexes for the palette : dataCount: the number of data elements in the array : targetColorArray: the LED array to store the resulting colors into. When I place 'void NewKit't function inside the semicolon, above void SetupRedBlueAndWhitePalette() /// @file ColorPalette. Change color of LEDs which are on This sketch is a compilation of the FastLED Color Palette and a button press. FastLED WS2812B ATtiny85 color change with button. #include "FastLED. addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS); there is no color order option to change. Is there some way to redefine that? Here's an example: #include "FastLED. However, I've been really trying to make other Fastled sketches work with it, specifically See row 529 of fastLED. FASTLED_FORCE_INLINE bool operator== (const CHSV &lhs, const CHSV &rhs) Check if two CHSV objects have the same color data. led[1] flickers, if i change the collor order it just flickers in a different color. addLeds<WS2812B, PIN_LEDS>(leds, NUM_LEDS); Share Add a Functions and class definitions for color palettes. Delay makes no difference same effect. In fact, it’s on this ability that LEDs can achieve desired light colors. I haven't included all my code as it is just a small problem. For more examples see this [link](examples). I expecting a plane dark aqua color, but it shows me a dark green and purple led instet of the dark aqua color. fadeLightBy() (everytime you want to change a color, you would set a 'HSV' color in the second array, convert that array to 'RGB' by using FASTLED_FORCE_INLINE CRGB & setHue (uint8_t hue) Allow assignment from just a hue. But I'm still not happy with the color transitions, I was able to get it a bit better using FastLED. This class manages controllers, global settings, and trackings such as brightness and refresh rates, and provides access functions for driving led data to controllers via the show() / I do not recommend you to change color order, because it work corectly with all led strips FastLED. That's because NEOPIXEL is hardcoded to use GRB. addLeds So this is a two part question. Create another variable that is the blend value of the LED and decrease it steadily over time. See an example of how to use FastLED to do ColorCorrection. It produces a range of colors that may not necessarily be actual white color. Take a look at some the the examples and see if you can get some of those running. Can some one help? The code: #include <EEPROM. I need it to fade from color to color I'm using an esp8266 with a web interface to control my ws2812b panel. i have attached the code, I just Reduce the brightness of an array of pixels as thought it were seen through a transparent filter with the specified color. Help your fellow community artists, makers and engineers out where you can. pal: the color palette to pull colors from : brightness: optional brightness value used to scale the resulting color : opacity a pointer to the color array to fill : numLeds: the number of LEDs to fill : c1: the starting color in the gradient : c2: the first middle color for the gradient : c3: the second middle color for the gradient : c4: the end color for the gradient : Approximate "black body radiation" palette, akin to the FastLED HeatColor() function. This is instantiated as a global object with the name FastLED. I have not fully tested this but it seems like the first and the last LEDs cannot be set. The FastLED library has a variety of color-control functions to help you animate faster. Short version i want the leds to light when one switch is pressed and to change color palettes when a second switch is pressed. Basically I have a void for each color (set like this: fill_solid(leds, 6, CRGB(0, 255, 0));), and call them when FastLED. Must be at least as long as dataCount. addLeds<LED_TYPE, DATA_PIN, COLOR_ORDER>(leds, NUM_LEDS); By using FastLED. Create CHSV objects for the color you are starting from and the color you are ending up with. 110 #define COOL_LIKE_INCANDESCENT 1. Is there any way I can change the color; fade it up to full brightness again; Fading to black, ok, I use: leds*. print() are for a debug purpose and can be removed once it works. FASTLED_FORCE_INLINE CRGB A variety of functions for working with color, palettes, and leds . ino #define COLOR_ORDER RGB: #define LED_TYPE WS2811 // i'm using WS2811s, FastLED supports lots of different types. We will also see how we can code to design our own color patterns. Now color temperature, measured in kelvins, describes how warm (red) or cool (blue) a light appears. Problem 1: I would like to randomly select a pattern from a predefined list of patterns. 2: change to FastLED. Practice by modifying existing sketches to change how they look. dwap aqp bse ptrk geyon zdgyl aae mybsiq tirrd vxevmxi
