Trigger external loads like lamps, fans, home appliances, garage doors, and other things, in an easy way using this Relay Shield. Simple and easy to use, the Relay Shield is compatible with the Ethernet Shield, allowing the triggering of distance loads via Internet.

Trigger the relays of RelayShield just by writing pins 7 and 8 of your Arduino, when these pins are at HIGH position, the relay triggers the load, when they are at LOW position the relay turns it off.

The state of each trigger door could be observed through the LEDs on RelayShield itself.
