3 Turns on an LED on for one second, then off for one second, repeatedly.
5 This example code is in the public domain.
8 // Pin 13 has an LED connected on most Arduino boards.
12 // the setup routine runs once when you press reset:
14 // initialize the digital pin as an output.
18 // the loop routine runs over and over again forever:
20 digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
21 delay(1000); // wait for a second
22 digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
23 delay(1000); // wait for a second
27 1. Aggiungere un secondo LED e farlo brillare ogni 500ms
28 mentre il primo brilla ogni 1000ms
29 2. Cosa succederebbe se dovessi anche leggere un input da un sensore / bottone?
