<span class="cm"> Version 1.1 January, 2019</span>
<span class="cm"> Based on Ken Shirriff's IrsendDemo Version 0.1 July, 2009,</span>
<span class="cm"> Copyright 2009 Ken Shirriff, http://arcfn.com</span>
<span class="cm"> An IR LED circuit *MUST* be connected to the ESP8266 on a pin</span>
<span class="cm"> as specified by kIrLed below.</span>
<span class="cm"> TL;DR: The IR LED needs to be driven by a transistor for a good result.</span>
<span class="cm"> Suggested circuit:</span>
<span class="cm"> https://github.com/crankyoldgit/IRremoteESP8266/wiki#ir-sending</span>
<span class="cm"> Common mistakes & tips:</span>
<span class="cm"> * * Don't just connect the IR LED directly to the pin, it won't</span>
<span class="cm"> have enough current to drive the IR LED effectively.</span>
<span class="cm"> * * Make sure you have the IR LED polarity correct.</span>
<span class="cm"> See: https://learn.sparkfun.com/tutorials/polarity/diode-and-led-polarity</span>
<span class="cm"> * * Typical digital camera/phones can be used to see if the IR LED is flashed.</span>
<span class="cm"> Replace the IR LED with a normal LED if you don't have a digital camera</span>
<span class="cm"> when debugging.</span>
<span class="cm"> * * Avoid using the following pins unless you really know what you are doing:</span>
<span class="cm"> * * Pin 0/D3: Can interfere with the boot/program mode & support circuits.</span>
<span class="cm"> * * Pin 1/TX/TXD0: Any serial transmissions from the ESP8266 will interfere.</span>
<span class="cm"> * * Pin 3/RX/RXD0: Any serial transmissions to the ESP8266 will interfere.</span>
<span class="cm"> * * ESP-01 modules are tricky. We suggest you use a module with more GPIOs</span>
<span class="cm"> for your first time. e.g. ESP-12 etc.</span>
