THINGS MIKE MADE
a cheap Wireless outlet switch
My boss and I made a wireless switch for much cheaper than you can get online (
excluded). We used a NodeMCU and
these 3V relay switches
The circuit we made is pretty simple. The NodeMCU is the brains, and uses
as well as a momentary button that we connected with a digital pin to control a relay. The relay opens and closes the 120V AC wall outlet. I've uploaded the code below.
