Here’s a nice ‘because I can’ style hack for a light switch 🙂
Will Donaldson has whipped up a quick hack…This remote switch uses a sg90 servo, an Arduino Uno, and pairs of ATtiny85s with HC-05 Bluetooth modules assembled on protoboards. The 3D printed mount screws easily on top of a standard light switch cover while still allowing the switch to be flipped the old-fashioned way.
