Introduction: How to Add an IR Remote to a Speaker System
In this project I will show you how I created an additional circuit for my speaker system in order to control it wirelessly with a homemade IR remote. Let's get started!
Step 1: Watch the Video!
The video gives you an overview on what you need to do to create your own IR receiver and transmitter. During the next steps I will present you additional information.
Step 2: Order Your Parts!

Step 3: Create the Circuit!
Here you can find the schematic as well as reference pictures for the transmitter and receiver. You can also find the schematic here: https://easyeda.com/GreatScott/IRRemote-j0cMKIGfh
Step 4: Upload the Code!
Here you can download the code that you need upload to your Arduino Pro Mini and ATmega328-PU before testing out your circuits.
Remember to download and include the necessary libraries in your folder:
