You could even up the ante and make even cooler animations by using palettes. What I like about FastLED that I haven't seen with other standalone libraries is
  3. You could try something like this for a rainbow chase. Add in your main loop: uint8_t hueRate = 20; // Effects cycle rate. (range >0 to 255) fill_rainbow( leds, NUM_LEDS, millis()/hueRate); // Start hue effected by time. FastLED.show(); delay(100); // Adjust as needed. Not necessarily required
  4. fill_rainbow (struct CRGB *pFirstLED, int numToFill, uint8_t initialhue, uint8_t deltahue=5) fill_rainbow - fill a range of LEDs with a rainbow of colors, at full saturation and full value (brightness) void fill_rainbow (struct CHSV *targetArray, int numToFill, uint8_t initialhue, uint8_t deltahue=5
  5. at the moment im struggeling with creating a small app to trigger a rainbow effect on a WS2812B LED Stripe with FASTLed, after pressing a button. After the end of the running rainbow, i will change to a standard LED state. This state represents some fields with dark and light colors. 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. I expecting a plane dark aqua color.

I have done a simple rainbow effect like this: //EFFECT RAINBOW if (effectString == rainbow) { // FastLED's built-in rainbow generator static uint8_t starthue = 0; thishue++; fill_rainbow(leds, NUM_LEDS, thishue, deltahue); if (transitionTime == 0 or transitionTime == NULL) { transitionTime = 130; } showleds(); Not sure what you mean by colorwipe but this will move the rainbow effect through the leds: void colorwipe() {//FastLED event scheduler EVERY_N_MILLISECONDS( 100 ) {hue++;} //FastLED rainbow function fill_rainbow( leds, NUM_LEDS, hue, 7);} Christopher_Ramey (Christopher Ramey) March 14, 2019, 11:34pm #3. This part I know, but I don't want the entire strip to come on at once, but rather one. This effect looks best when hanging your LED strip vertical and it simulates a one LED wide fire, and is adapted from an example in FastLED, which is adapted from work done by Mark Kriegsman (called Fire2012). Note that this effect looks awesome when using diffuse light! This function takes 3 parameters void rainbow {// FastLED's built-in rainbow generator: fill_rainbow ( leds, NUM_LEDS, gHue, 7);} void rainbowWithGlitter {// built-in FastLED rainbow, plus some random sparkly glitter: rainbow (); addGlitter (80);} void addGlitter ( fract8 chanceOfGlitter) {if ( random8 < chanceOfGlitter) {leds[ random16 (NUM_LEDS) ] += CRGB::White;}} void confett So far I managed to get the basics done (same static color for each led, color fade with each leds simultaneous). I got a rainbow effect working, but its basically only a cycle through the color spectrum for all leds at the same time. What I want is a rainbow wave, where the colors are moving in one direction and fading into/chasing each other

Here are several display sequences for FastLED for a single strand of addressable RGB LED's, such as NeoPixels/WS2812, WS2801 or DotStars/APA102. Each should compile and run separately and all have been tested on an Arduino Nano with appropriate inputs as required. Almost all of these sequences are designed to be loop/non-blocking delay friendly. They perform some simple calculations, update the LED array, return back to the loop to SHOW the LED's and then continue on to the next iteration

All the functions (rainbow, juggle, etc) just need to work on your leds[] array that you gave to FastLED.addLeds() in your setup()-- I assume that your functions already fulfill that requirement. But: All functions must have the same argument list (in this case: they must be defined like void rainbow() { leds[x] = CHSV(a,b,c); } ), so you might need to wrap them in another function he guys on this video I showed you how to use ws2812b adressable led strip with arduino and how to make rainbow effectsparts you need:arduino unows2812bthere..

I should put in a warning message when that's happening - AVR/arduino's ISR handling is so slow that even the clock tick ISR would be enough to disrupt writing out WS2812 data (resulting in FastLED cutting the frame off) so I yanked that code out of the avr WS2812 asm implementation As the FastLED supports many more LED strips (different LED modules, different lengths, etc.), the initialization needs the LED module type, Arduino pin number used for data transfer, color order, reference to an array representing the LEDs, and the number of LEDs. Optionally, a color correction can be set in order to improve the fidelity of the colors. Next, there is a function which switches.
