Since you probably don’t use most of the buttons on your remote control, why not make them work for other things? This project shows you how to use an Arduino to decode the signal from a remote and then use it to make an outlet switch keyed to that code.P
This little hack comes from one of our favorite Instructables users, DIY Hacks and How Tos. To build this project, you’ll need an Arduino, an infrared receiver module, some LEDs, switches, and a few other electronic odds and ends. When you’re done, you’ll be able to power on or off pretty much anything you want using your TV remote. And yes, you can buy remote outlets with separate controls, but this one lets you use a control you already have. Plus, it’s an excellent learning project if you’re just getting started with Arduino.
