/*
* IRremoteESP8266: IRrecvDemo - demonstrates receiving IR codes with IRrecv
* This is very simple teaching code to show you how to use the library.
* If you are trying to decode your Infra-Red remote(s) for later replay,
* use the IRrecvDumpV2.ino example code instead of this.
* An IR detector/demodulator must be connected to the input RECV_PIN.
* Copyright 2009 Ken Shirriff, http://arcfn.com
* Example circuit diagram:
* https://github.com/markszabo/IRremoteESP8266/wiki#ir-receiving
* Changes:
* Version 0.2 June, 2017
* Changed GPIO pin to the same as other examples.
* Used our own method for printing a uint64_t.
* Changed the baud rate to 115200.
* Version 0.1 Sept, 2015
* Based on Ken Shirriff's IrsendDemo Version 0.1 July, 2009
