Programación

Primeros bocetos con processing con arduino.
1) Titilar un led (de la placa o conectado al pin 13)
 
void setup() {
pinMode(13,OUTPUT);
}
void loop() {
  digitalWrite(13,HIGH);
  delay(1000);
  digitalWrite(13,LOW);
  delay(1000);
}

Codigo 2
void setup() {
  pinMode(2, OUTPUT);
  pinMode(3, OUTPUT);
}
void loop() {
  digitalWrite(2, HIGH);
  delay(1000);
  digitalWrite(2, LOW);
  delay(1000);
  digitalWrite(3, HIGH);
  delay(1000);
  digitalWrite(3, LOW);
  delay(1000);

}

Codigo 3
void setup() {
  pinMode(2, OUTPUT);
  pinMode(3, OUTPUT);
}
void loop() {
  digitalWrite(2, HIGH);
  delay(1000);
  digitalWrite(2, LOW);
  delay(1000);
  digitalWrite(3, LOW);
  delay(1000);
 digitalWrite(3, HIGH);
  delay(1000);
}
