/*
  Blink
 Turns on an LED on for one second, then off for one second, repeatedly.

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int ledA = 13; //Primo LED
int ledB = 12; //Secondo LED

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(ledA, OUTPUT);    
  pinMode(ledB, OUTPUT);  
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(ledA, HIGH);   // turn the LED on (HIGH is the voltage level)
  digitalWrite(ledB, HIGH);

  delay(500);               
  digitalWrite(ledB, LOW);

  delay(500);
  digitalWrite(ledA, LOW);
  digitalWrite(ledB, HIGH);


  delay(500);               
  digitalWrite(ledB, LOW);

  delay(500);
  digitalWrite(ledA, LOW);
  digitalWrite(ledB, LOW);

/* Domande
 1. Aggiungere un secondo LED e farlo brillare ogni 500ms
 mentre il primo brilla ogni 1000ms
