8 // Pin 13 has an LED connected on most Arduino boards.
15 // the setup routine runs once when you press reset:
17 // initialize the digital pin as an output.
22 // the loop routine runs over and over again forever:
29 digitalWrite(red, HIGH); // turn the LED on (HIGH is the voltage level)
30 delay(lunga); // wait for a second
31 digitalWrite(red, LOW); // turn the LED off by making the voltage LOW
36 digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
37 delay(breve); // wait for a second
38 digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
39 delay(breve); // wait for a second
