-// Pin 13 has an LED connected on most Arduino boards.
-// give it a name:
+// Pin 13 ha un LED collegato di default
int led = 13;
-// the setup routine runs once when you press reset:
void setup() {
- // initialize the digital pin as an output.
+ // Inizializziamo il PIN 13 come OUTPUT
pinMode(led, OUTPUT);
}
-// the loop routine runs over and over again forever:
void loop() {
- digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
- delay(1000); // wait for a second
- digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
- delay(1000); // wait for a second
+ digitalWrite(led, HIGH);
+ delay(1000);
+ digitalWrite(led, LOW);
