...to try and understand how it all hangs together in Arduino land....

That would be a reasonable way of putting it.
Arduino code UI is convenient for rapid development of small projects, but a pain in the a$$ when you want to do things properly!
Best to learn what yoiu can about C/C++ and keep the hardware, and lose the UI

Description

A byte stores an 8-bit unsigned number, from 0 to 255. 

Looks pretty accurate to me.
