Learn how to add IR(infrared) remote to your Arduino projects. I am using a free Arduino simulator to demonstrate it. Let's begin!!!

Explain each section of your project

Introduction

It is so easy to add IR remote to your projects. In this tutorial, I will show you how to easily add an IR remote and an IR receiver for your next Arduino project. I am using a free Arduino simulator to demonstrate IR receiver and IR remote projects.

Components needed

  • Arduino Nano (Arduino UNO) can also be used
  • IR receiver
  • IR transmitter (IR Remote)
  • LCD (optional, to display the pressed key information)

IR remote basics

There is a wonderful article here on Adafruit learning page
