In this video I hack apart some household 433mhz wall switches to make a wireless gameshow buzzers. Note that you can pretty much hack anything with 433mhz and a button do this, I just had a bunch of these left over from another project.

The code:
The code is meant to be simple and easy to understand.
I avoid using a lot of techniques noobs would have a hard time understanding.

Important info below if you want to simplify this build.
Key Components:
Project Boxes:
433 Receivers:

Keychain –

Switches – Please note that you can use all keychains instead of these switches. If you use the 1 button keychain, you don’t even need to build the project boxes at all.
