sketch h cpp

is there anything online that can explain how my sketch communicates with .h and .cpp i really have no concept of how this stuff works.

and i have been playing with this stuff for over two years. i'm tired of now knowing what i'm doing. all the stuff i've made works, but I'd like to know more.

Thank you.

Strange. I find that I never get tired of knowing what I’m doing. What tires me out is NOT knowing what I’m doing.
