= Relay Actuator With Pushbutton  =

This example show how to control an relay from Vera and also locally with a push button connected to the Arduino. Local status changes of the relay state will be transmitted to Vera.

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

== Wire things up ==

Follow the instructions in ConnectingRadioModule to connect radio module.
[[Image(digital_button.jpg, width=250px, align=right)]]
Connect the IN1 of relay to digital pin 4 of Arduino board.\\
Connect Relay VCC to +5V of the Arduino board. GND to GND.\\
Connect push button between +5V and digital pin 3 with a 10k pull down resistor to GND (see image).

== Hardware - Purchase guide ==

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