2  * The MySensors Arduino library handles the wireless radio link and protocol
3  * between your home built sensors/actuators and HA controller of choice.
4  * The sensors forms a self healing radio network with optional repeaters. Each
5  * repeater and gateway builds a routing tables in EEPROM which keeps track of the
6  * network topology allowing messages to be routed to nodes.

21  * DESCRIPTION
22  *
23  * Interrupt driven binary switch example with dual interrupts
24  * Author: Patrick 'Anticimex' Fallberg
25  * Connect one button or door/window reed switch between
26  * digital I/O pin 3 (BUTTON_PIN below) and GND and the other
27  * one in similar fashion on digital I/O pin 2.
28  * This example is designed to fit Arduino Nano/Pro Mini
