Blink v1
Accensione e spegnimanto di un LED utilizzando variabili
per impostare la velocita' del lampeggio.
- Turns on an LED on for one second, then off for one second, repeatedly.
-
- This example code is in the public domain.

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
int breve = 200; // Variabile richiambile nel corso dell'esecuzione
int lunga = 1000;
-// the setup routine runs once when you press reset:
+// /////////////////
+// Setup: eseguita una volta sola all'accensione della scheda
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
-// the loop routine runs over and over again forever:
+// ///////////////
+// loop: Le istruzioni vengono eseguite all'infinito
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(breve); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(breve); // wait for a second
- digitalWrite(red, HIGH); // turn the LED on (HIGH is the voltage level)
+ digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(lunga); // wait for a second
- digitalWrite(red, LOW); // turn the LED off by making the voltage LOW
+ digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(lunga);
