Description

Use the Arduino to control a light emitting diode and make it blink.
Components Used

* Light Emitting Diode (LED)
* Resistor

Arduino Code

/* Blinking LED
* ------------
*
* turns on and off a light emitting diode(LED) connected to a digital
* pin, in intervals of 2 seconds. Ideally we use pin 13 on the Arduino
* board because it has a resistor attached to it, needing only an LED

int ledPin = 13; // LED connected to digital pin 13

void setup()
{
pinMode(ledPin, OUTPUT); // sets the digital pin as output
}

void loop()
{
digitalWrite(ledPin, HIGH);   // sets the LED on
delay(80000);                  // waits for a 8 seconds
digitalWrite(ledPin, LOW);    // sets the LED off
delay(500);                  // waits for half of a second
