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 ​here

Wire things up

Follow the instructions in ConnectingRadioModule to connect radio module. 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).
