Turn off (or on) any television set via Bluetooth and IR light! This project combines the ever-popular IR blaster concept with an additional layer of remoteness -- Bluetooth Low Energy! Plant the device near your target and then safely trigger it with your phone from another location.
The Circuit Playground Bluefruit combined with the STEMMA High Power Infrared LED Emitter, running CircuitPython makes it simple to build this super sneaky device.
This project is a riff on the excellent Circuit Playground Express TV Zapper project, check out the guide here for the history of the TV-B-Gone as well as tons of details on the process of creating the IR remote code file for use with CircuitPython!
