/*
* ReceiveDemo.cpp
*
* Demonstrates receiving IR codes with the IRremote library and the use of the Arduino tone() function with this library.
* Long press of one IR button (receiving of multiple repeats for one command) is detected.
* If debug button is pressed (pin connected to ground) a long output is generated, which may disturb detecting of repeats.
*
