/* IRremoteESP8266: IRsendDemo - demonstrates sending IR codes with IRsend.

   Version 1.1 January, 2019
   Based on Ken Shirriff's IrsendDemo Version 0.1 July, 2009,
   Copyright 2009 Ken Shirriff, http://arcfn.com

   An IR LED circuit *MUST* be connected to the ESP8266 on a pin
   as specified by kIrLed below.

   TL;DR: The IR LED needs to be driven by a transistor for a good result.

   Suggested circuit:

   Common mistakes & tips:
 *   * Don't just connect the IR LED directly to the pin, it won't
       have enough current to drive the IR LED effectively.
 *   * Make sure you have the IR LED polarity correct.
       See: https://learn.sparkfun.com/tutorials/polarity/diode-and-led-polarity
 *   * Typical digital camera/phones can be used to see if the IR LED is flashed.
       Replace the IR LED with a normal LED if you don't have a digital camera
       when debugging.
 *   * Avoid using the following pins unless you really know what you are doing:
 *     * Pin 0/D3: Can interfere with the boot/program mode & support circuits.
 *     * Pin 1/TX/TXD0: Any serial transmissions from the ESP8266 will interfere.
 *     * Pin 3/RX/RXD0: Any serial transmissions to the ESP8266 will interfere.
 *   * ESP-01 modules are tricky. We suggest you use a module with more GPIOs
       for your first time. e.g. ESP-12 etc.
