Hack A Laser Tag Toy Into A Smart Home Sidekick!

About the project

Ill show you how to replace the brains of a laser tag toy to make a universal remote! All of the electronics still work without toy!

I wanted to make a universal remote that was more interesting than just some box with buttons on it. My idea was to take a Nerf blaster and replace the mechanisms inside with a circuit that would work as an IR remote. While looking for a blaster I stumbled upon a home laser tag toy that uses IR already. Since it already had a battery holder, electronic trigger, and built in IR LED it was perfect. I made this video to talk about it and show off how it works!

This shows how to wire up the pro mini



This is the main code that should be uploaded to the pro mini


This code defines the pins for using the IR led
