Blink_500_delay.ino

//
// Blink
//
// The basic Arduino example. Turns an LED on for one second,
// then off for one second, and so on forever ... or until you
// turn the Duinobot off.
//
// We use pin 13 as depending on the Arduino board
// (the Duinobot in our case), it has either:
// - a built-in LED or,
// - a built-in resistor so that you only need to add an LED.
//
// NOTES:
// - The Duinobot has an LED so we do not have to add anything.
// - See http://www.arduino.cc/en/Tutorial/Blink for the original
// tutorial.

int ledPin = 13; // LED connected to digital pin 13
 
void setup() // run once, when the sketch starts
{
pinMode(ledPin, OUTPUT); // sets the digital pin as output
}
 
 
void loop() // run over and over again
{
digitalWrite(ledPin, HIGH); // sets the LED on
delay(500); // waits for a second
digitalWrite(ledPin, LOW); // sets the LED off
delay(500); // waits for a second
}
