Basically, the bigger picture, wanting to dust off my theory in electronics, I planned to add a bit of convenience to my house. This ranges from controlling my lights, garage, entertainment system, remotely. To brush up on my electronic literature, I wanted to do all this from scratch, component by component..
For the sake of this instructable, I scaled down the contents of this tutorial to addressing only how I made 2 way switching possible via RPI.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
