+*
+* 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.
