esp8266 code

/*
 * 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
