Introduction: Blinking LED

Picture of Blinking LED

In this project we will be using arduino to control a LED to blink at different rate.

It's a very simple project to get started with arduino. We have included the video tutorial as well.

So lets get started....

Step 1: Components Required

Picture of Components Required

To make this you will require

>Arduino Uno

>Jumper Wires

>LED

>220 ohms resistor (x1)

>breadboard

Step 2: Assemble LED

Connnect the LED as follows

- Connect cathode to power rail(blue rail) which supplies with ground from the Arduino.

- Now connect the anode to a node on your breadboard.

Step 3: Connect Current Limiting Resistors

- Connect 220 ohms resistor in series with the anode of LED.

- The resistors are used to control the amount of current.

Step 4: Connect LED With Arduino
