= Relay Actuator =

== Software ==
You can download the Arduino sketch [[https://github.com/mysensors/Arduino/tree/master/libraries/MySensors/examples/RelayActuator|here]]\\

== Wire things up ==

Follow the instructions in ConnectingRadioModule to connect radio module.

Connect the IN1 and IN2 of relay to digital pin 3,4 of Arduino board.\\
Connect VCC to +5V of the Arduino board. GND to GND.\\

I used a dual relay module. But the code can easily be adapted to handle more or less relays by modifying RELAY_1 (which digital input first relay is connected to) and NUMBER_OF_RELAYS defines at the top of the sketch code.

== Hardware - Purchase guide ==

To build this sensor you'll need one arduino + radio specified in the base kit found here:\\
