AJLElectronics:
I haven't got to the bottom of the clash in libraries yet. The sketch compiles and uploads fine until I #include <IRremote.h> when I get:C:\Users\Andy\AppData\Local\Temp\arduino_build_452047\libraries\IRremote\IRremote.cpp.o (symbol from plugin): In function `MATCH(int, int)':

Error compiling for board Arduino Nano.
I think the problem is that my iBus library, and that IRremote library are using the same ISR. Interestingly, it actually compiles fine on my system, so may have a different IRremote library installed.
This is the header from the IRremote.h file in the library I have.

I guess this library doesn't use the same ISR. Maybe worth a look.
