Blinking LED

Project Members: 
Aylin Selcukoglu


Make the LED (Light Emitting Diode) blink using the Arduino board.

Components Used

LED (Light Emitting Diode)
20-ohm resistor (red, red, brown, gold)

Arduino Code

/* Blinking LED
* ------------
* Created September 5, 2007  
* Turns on and off a LED connected to digital pin 13. Pin 13 has a
* resistor attached to it requiring only the LED to make this work.
* For the sake of practice, the circuit with the resistor was created. 
 * based on:

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(1000); // waits for a second
digitalWrite(ledPin, LOW); // sets the LED off
delay(1000); // waits for a second
