I wanted to control the light switch in my bedroom without having to get out of bed, so I wanted to be able to control it from my phone. I had a few extra constraints, I wanted to be able to control it from any device easily, I wanted to be able to use the light switch as normal and I couldn’t make much modification to the hardware as I rent the apartment.
I decided to use a Raspberry Pi to control a servo motor which would move the switch. The Raspberry Pi would run a web server that I could access while on the local network. Links on the website on this server would allow me to turn the switch on and off. By de-energizing the servo between switching I could also still use the lightswitch as normal.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
