 Turns on an LED on for one second, then off for one second, repeatedly.
// the setup function runs once when you press reset or power the board
void setup() 
 // initialize digital pin 13 as an output.
 pinMode(2, OUTPUT);
// the loop function runs over and over again forever
void loop()
 digitalWrite(2, HIGH); // turn the LED on (HIGH is the voltage level)
 delay(1000); // wait for a second (1000 mSeconds) 
 digitalWrite(2, LOW); // turn the LED off by making the voltage LOW
 delay(1000); // wait for a second (1000 mSeconds)
