# PROGRAMMER ... Options to avrdude which define the hardware you use for
# uploading to the AVR and the interface where this hardware
# is connected.
# FUSES ........ Parameters for avrdude to flash the fuses appropriately.

Thank you for great tutorial. It helped me getting started, which is kind of the hardest thing. Anyway, I have a question:
Unfortunately I don't really know how makefiles work and I can barely edit or customize them. Now I split my code into multiple files, that I included in main.c. What do I have to modify in the makefile so that the compiler knows, what to compile? I could not get it to work. It's probably very easy and maybe you can help me out. This would be great.
Kind regards, Klaus.
