// MultiArrays - see https://github.com/FastLED/FastLED/wiki/Multiple-Controller-Examples for more info on // using multiple controllers. In this example, we're going to set up three NEOPIXEL strips on three // different pins, each strip getting its own CRGB array to be played with #include #define NUM_LEDS_PER_STRIP 60 CRGB redLeds[NUM_LEDS_PER_STRIP]; CRGB greenLeds[NUM_LEDS_PER_STRIP]; CRGB blueLeds[NUM_LEDS_PER_STRIP]; // For mirroring strips, all the "special" stuff happens just in setup. We // just addLeds multiple times, once for each strip void setup() { // tell FastLED there's 60 NEOPIXEL leds on pin 10 FastLED.addLeds(redLeds, NUM_LEDS_PER_STRIP); // tell FastLED there's 60 NEOPIXEL leds on pin 11 FastLED.addLeds(greenLeds, NUM_LEDS_PER_STRIP); // tell FastLED there's 60 NEOPIXEL leds on pin 12 FastLED.addLeds(blueLeds, NUM_LEDS_PER_STRIP); } void loop() { for(int i = 0; i < NUM_LEDS_PER_STRIP; i++) { // set our current dot to red, green, and blue redLeds[i] = CRGB::Red; greenLeds[i] = CRGB::Green; blueLeds[i] = CRGB::Blue; FastLED.show(); // clear our current dot before we move on redLeds[i] = CRGB::Black; greenLeds[i] = CRGB::Black; blueLeds[i] = CRGB::Black; delay(100); } for(int i = NUM_LEDS_PER_STRIP-1; i >= 0; i--) { // set our current dot to red, green, and blue redLeds[i] = CRGB::Red; greenLeds[i] = CRGB::Green; blueLeds[i] = CRGB::Blue; FastLED.show(); // clear our current dot before we move on redLeds[i] = CRGB::Black; greenLeds[i] = CRGB::Black; blueLeds[i] = CRGB::Black; delay(100); } }
