Good morning everybody,
In a few words, my problem is as follows:
I cannot compile a sketch...
It always gives me a "fatal error: I2C.h: No such file or directory" message.
I understand that the IDE is searching to include a file or a directory named "I2C.h" which it cannot find.
And...
I could not find it in my "library directory" either...
The sketch will be run on an Arduino Nano.
Hence, I'll pay for the beers if somebody would be so nice and help me through this problem.
Please see below the sketch in question (thanks to the original author...)
and further down, my error message...
Thanks a million for your time...
