Overview

Build your own Bluetooth, remote-controlled robotic light switch to turn on and off the lights! Using CircuitPython running on the Feather nRF52840 Express and Crickit FeatherWing to flip the switch with a servo motor, you can avoid all of the complexities and dangers of high voltage mains wiring!

The 3D printed actuator, mount, and case makes it reliable and tidy. And the Adafruit Bluefruit app running on your iOS or Android device makes it fun and easy!
