Product Description
The relay shield is controlled through pin Digital 4 on your Arduino via a transistor labeled Q1 . When output Digital 4 on your Arduino is low, the relay shield will connect the NC pin to the Common pin of the screw terminal. When output Digital 4 goes high, the Coil On LED will light up and the relay shield will instead connect the NO pin to the Common pin of the screw terminal.
The Relay Shield is sold as an easy-to-assemble kit and includes everything listed below with clear assembly instructions listed in the documents section.
