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!
