/ NeoPixel Ring simple sketch © 2013 Shae Erisson released under the GPLv3 license to match the rest of the AdaFruit NeoPixel library #include <Adafruit_NeoPixel.h> #include <avr/power.h> Which pin on the Arduino is connected to the NeoPixels? On a Trinket or Gemma we suggest changing this to 1 #define PIN1 3 jaune #define PIN2 6 vert How many NeoPixels are attached to the Arduino? #define NUMPIXELS1 5 jaune #define NUMPIXELS2 5 vert

When we setup the NeoPixel library, we tell it how many pixels, and which pin to use to send signals. Note that for older NeoPixel strips you might need to change the third parameter–see the strandtest example for more information on possible values. Adafruit_NeoPixel pixels1 = Adafruit_NeoPixel(NUMPIXELS1, PIN1, NEO_GRB + NEO_KHZ800); jaune Adafruit_NeoPixel pixels2 = Adafruit_NeoPixel(NUMPIXELS2, PIN2, NEO_GRB + NEO_KHZ800); vert void setup() { pixels1.begin(); This initializes the NeoPixel library.

pixels2.begin(); // This initializes the NeoPixel library.
Serial.begin(9600);

}

void loop() {

// For a set of NeoPixels the first NeoPixel is 0, second is 1, all the way up to the count of pixels minus one.
pixels1.show();
pixels2.show();

for(int i=NUMPIXELS1;i>=0;i--){
  Serial.print("DELS1 : ");
  Serial.println(i);
   allumer1(i,2); 
   delay(15); // Delay for a period of time (in milliseconds).
   }

for(int i=0;i<NUMPIXELS2;i++){
   Serial.print("allume DEL 2: ");
   Serial.println(i);
   allumer2(i,2);

    eteindre(i,5);
    delay(20); // Delay for a period of time (in milliseconds).
    }
    */
