This library enables you to send and receive infra-red signals on an ESP8266 using the Arduino framework using common 940nm IR LEDs and common IR receiver modules. e.g. TSOP{17,22,24,36,38,44,48}* etc.
Version 2.5.4 of the library is now available. You can view the Release Notes for all the significant changes.
Usage of the library has been slightly changed in v2.0. You will need to change your usage to work with v2.0 and beyond. You can read more about the changes required on our Upgrade to v2.0 page.
The library has changed from using constants declared as #define to
const with
the appropriate naming per the
C++ style guide.
This may potentially cause old programs to not compile.
The most likely externally used #defines have been aliased for limited
backward compatibility for projects using the old style. Going forward, only the
new kConstantName style will be supported for new protocol additions.
In the unlikely case it does break your code, then you may have been referencing
something you likely should not have. You should be able to quickly determine
the new name from the old. e.g. CONSTANT_NAME to kConstantName.
Use common sense or examining the library's code if this does affect code.

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.
