Do you want to control your lights or appliances using a microcontroller? Build an internet-connected electrical outlet with an Adafruit PyPortal and CircuitPython. The guide uses a controllable four outlet power relay to avoid hazardous high voltages. Connect the project to Adafruit IO, our free Internet-of-Things platform, to control your appliances from anywhere in the world.


Adafruit IO Dashboard

Adafruit IO is the easiest way to stream, log, and interact with your data. It's built from the ground up to be easy to use - we do the hard stuff so you can focus on the fun stuff.

You'll build a customizable dashboard to turn your A/C appliance on or off and can optionally add extra blocks to read feedback from the appliance
