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

Section Header

Explain each section of your project

Arduino IR remote project on Wokwi Arduino Simulator

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

https://learn.adafruit.com/ir-sensor/ir-remote-signals

Another resource I found which is helpful
