It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go.

As the regular LEDs are too small to be noticeable, you can replace them with bigger LEDs or even a light bulb (paired with a relay for the Arduino Uno). Try a toggle switch instead, so you won't ...
