 Componenti:

• 5 cavetti MM
• 3 LED: verde, giallo e rosso
• 1 cicalino
• 3 resistenze di 220 Ω

 Il codice:

void setup()
{
  pinMode(3, OUTPUT); // cicalino
  pinMode(11, OUTPUT); // verde
  pinMode(10, OUTPUT); // giallo
  pinMode(9, OUTPUT); // rosso
}

void loop()
{
  digitalWrite(11, HIGH);
  delay(2500);

  for (int i = 0; i < 5; i++) {
    digitalWrite(3, HIGH);
    digitalWrite(10, HIGH);
    delay(500);
    digitalWrite(10, LOW);
    digitalWrite(3, LOW);
    delay(500);
  }

  digitalWrite(11, LOW);
  digitalWrite(10, HIGH);
  delay(1000);

  digitalWrite(10, LOW);
  digitalWrite(9, HIGH);
  delay(4000);

  digitalWrite(9, LOW);
