What's in the Box
The Evil Mad Scientist Simple Relay Shield is an Arduino add-on that lets you use your Arduino (or shield-compatible clone, such as the Diavolino) to control a single electromechanical relay, for switching loads of up to 24 V DC or 40 V AC, at up to 5 A of current. The relay is an "SPDT" type, meaning that it can be used either as a normally-open or normally-closed relay, so that you can choose to either switch on or switch off your load when the output signal from your Arduino is high. When operated as a normally-open relay, it is capable of handling loads up to 10A. The relay is powered directly from the 5V power supplied by your Arduino board, and is compatible with the vast majority of shield-compatible Arduino and Arduino-compatible boards, which operate at 5V.
