This is a tutorial showing how to turn outlets into smart plugs with a Circuit Playground Express. Use this power switch relay and arduino, CircuitPython or MakeCode to control the outlets. You can trigger on/off with any of the Circuit Playground's onboard sensors: turn lights on automatically when it gets dark, make a motion controlled on/off switch, use the sound sensor to trigger your lights, and much more.

No soldering required! This is a very easy project that's great for beginners.
