Use Arduino to Switch Power On and Off!By Robolab Technologies In Arduino
Mike picked up a $10 SainSmart 8 Channel DC 5V Relay Module, hooked it up to an Arduino micro controller (a Raspberry Pi should work, too!) and the next thing you know he’s remotely controlling 8 electrical devices… it’s like building an 8 channel remote, each relay on the board can handle some serious juice, up to 10A 230V AC, 30V 10A DC. It’s super easy to set up. Learn how in the video!
