  • Examples by Einstein
    • Using rgbcolors.h instead of rgb values in code

• • • Simple on in one color

1. include <Adafruit_NeoPixel.h>

1. define PIN 6
2. define NUM_LIGHTS 4

Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LIGHTS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {

 strip.begin();
 strip.show(); // Initialize all pixels to 'off'

}

void loop() {

 allon();

}

void allon() {

   uint32_t low = strip.Color(0, 0, 0); 
   uint32_t high = strip.Color(255,255,255);
 
   // Turn them off
   for( int i = 0; i<NUM_LIGHTS; i++){
       strip.setPixelColor(i, low);
       strip.show();
   }   

}

• • • Simple blink in one color
