/* 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:

* https://github.com/crankyoldgit/IRremoteESP8266/wiki#ir-sending

*

* 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.
