Motor rodando e código

Vídeo:

Código do blink adaptado para rodar um motor DC.
Dá para controlar a velocidade usando a saída PWM.

/*
  Motor1
  Turns on a motor on for one second, then off for one second, repeatedly.
 */

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int motor1 = 2;
int motor2 = 3;   // PWM output

// the setup routine runs once when you press reset:
void setup() {               
  // initialize the digital pin as an output.
  pinMode(motor1, OUTPUT);    
  pinMode(motor2, OUTPUT);    
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(motor1, HIGH);
  digitalWrite(motor2, LOW);
  delay(1000);
  digitalWrite(motor1, LOW);
  delay(1000);
}
