Project description
This multisense lamp can be triggered by a timer, sound (like a clapper), or touch. We use an electromechanical relay and an npn transistor to control the 120V outlet from the arduino. Sparkfun sells this small relay as well as a larger one that lets you control up to 5 AMPs!! with lil ol' arduino. This tutorial describes how to control high voltage AC with a low voltage DC microcontroller Be Careful!! High voltage can hurt you! Only solder on unplugged devices and test all connections before plugging anything into the mains power. Proceed at your own risk, friend. The code and all the details are available @ http://lucidtronix.com/tutorials/8
