Blink na 3 LED diode

Zadatak 1: Pokušajmo sada modificirati kod tako da blinkaju sve 3 LED diode.

Sketch

int led1 = 8;
int led2 = 9;
int led3 = 10;

// the setup routine runs once when you press reset:
void setup() {
  // initialize the digital pin as an output.
  pinMode(led1, OUTPUT);
  pinMode(led2, OUTPUT);
  pinMode(led3, OUTPUT);
}
