When I am using power tools in my workshop, I can’t hear the doorbell ring. I needed some other kind of system that can let me know when someone is at the front door, so I modified a wireless doorbell system to turn on a light in addition to playing a tone. Using wireless doorbells, you can set up multiple receivers without having to run wires all over your house. Here is how to make it.
