Led RGB

 

Código colores básicos

#define rojo 4     // definimos los pines del led

#define verde 5

#define azul 6

void setup(){

  pinMode (rojo,OUTPUT);

  pinMode (verde,OUTPUT);

  pinMode (azul,OUTPUT);

}

void loop() {

  // creamos color rojo

  digitalWrite (rojo,HIGH);

  digitalWrite (verde,LOW);

  digitalWrite (azul,LOW);

  delay (1000);  //esperamos 1s

  // creamos color verde

  digitalWrite (rojo,LOW);

  digitalWrite (verde,HIGH);

  digitalWrite (azul,LOW);

  delay (1000);  //esperamos 1s

  // creamos color azul

  digitalWrite (rojo,LOW);

  digitalWrite (verde,LOW);

  digitalWrite (azul,HIGH);

  delay (1000);  //esperamos 1s

 // creamos color amarillo

  digitalWrite (rojo,HIGH);

  digitalWrite (verde,HIGH);

  digitalWrite (azul,LOW);

   delay (1000);  //esperamos 1s

   // creamos color cian

  digitalWrite (rojo,LOW);

  digitalWrite (verde,HIGH);

  digitalWrite (azul,HIGH);  

  delay (1000);  //esperamos 1s

  // creamos color magenta

  digitalWrite (rojo,HIGH);

  digitalWrite (verde,LOW);

  digitalWrite (azul,HIGH);

    delay (1000);  //esperamos 1s
