This library enables you to send and receive infra-red signals on an ESP8266 or an ESP32 using the Arduino framework using common 940nm IR LEDs and common IR receiver modules. e.g. TSOP{17,22,24,36,38,44,48}* demodulators etc.
You can find the details of which protocols & devices are supported here.

This library was originally based on Ken Shirriff's work (https://github.com/shirriff/Arduino-IRremote/)
Mark Szabo has updated the IRsend class to work on ESP8266 and Sebastien Warin the receiving & decoding part (IRrecv class).
As of v2.0, the library was almost entirely re-written with the ESP8266's resources in mind.
