Here’s the problem: You have a light switch on your wall that you want to control over the internet. But you don’t want to mess with the house wiring — scary! — or damage the switch. What do you do?
Answer: Use a mechanical, motor-driven “finger” to flick the switch for you. As a bonus, you can still flip the switch normally, and can easily remove it when you’re done — essential if you rent your home. As with many engineering problems, it’s a tradeoff — you have an “internet thing” externally attached to your light switch. But if you don’t want to mess with house current or open up the light switch to conceal the apparatus, this is the way to go. It’s fun to have a tiny robot dedicated to flipping a switch whenever you say!
Each Monday is ArduinoMonday here at Adafruit! Be sure to check out our posts, tutorials and new Arduino related products. Adafruit manufactures the Arduino right here in the United States in cooperation with arduino.cc. We have a huge selection of Arduino accessories and all the code and tutorials to get you up and running in no time!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
