I got an error on line 44: fatal error: FuelGauge.h: No such file or directory
How can I fix this error?
Also, I would really appreciate if you tell me other errors that you've found.
Thank you.

Hi There

file you are referring is header file, #include "FuelGauge.h" this file should be located where is your main program .cpp located.
