Infrared remote controls are everywhere, you probably have several of them in your home. These handy devices work by sending coded signals with pulses of infrared light to control appliances. We take them for granted, but just imagine using your television or Blu-ray player without one!

In this video, I’ll show you how these handy devices work and how you can capture and decode their codes with an Arduino and some very inexpensive parts. You’ll also learn how to repurpose the remote controls you already own so that you can put those unused buttons to work controlling devices like lights and fans.

I’ll also show you how you can use an Arduino to build your own custom IR Remote Control. Control everything in your room with one button (if that's what you want to do).

Finally, we will see how to use those inexpensive remotes that you can get on eBay to add remote control capabilities to your own Arduino projects. I’ll present a simple project that uses one of those controls to adjust the position of a servo motor. It even uses the “repeat” function that isn’t very well documented.

Here is a breakdown of what we will cover in the video:

00:00 - Introduction
02:20 - How IR Remotes work
03:37 - How to “see” Infrared Light
04:56 - The IR Sensor
06:29 - Decoding IR Remote codes
10:07 - Getting Manufacturers Codes
13:22 - Repurposing an IR Remote
20:37 - Building a Custom IR Control
28:19 - Control a Servo

As always you’ll find an article with all of the code used here on the DroneBot Workshop website at https://dbot.ws/irarduino. The site also has links to resources you may need when working with IR Remote controls.

Now go ahead and start controlling your world!
