Hey everyone, I'm working my way through the 50$ robot, and its not very difficult to follow instructions/ wiring diagrams but I would like to know why I'm doing what I'm doing.
I've read through all the additional links provided in the guide but they all seem pretty generic. I was wondering if there is some sort of writeup on why these parts were chosen, what each of their purposes are in the circuit, etc.
For example how would you know what size capacitor to use if designing the circuit? Also, I don't really know what the ATmega8 does, or how it works, or what each of the pins are for beyond the short forms on the diagram.
Anyway, that's the kind of info I'm looking for, if anyone could point me in the right direction that would be great. Thanks!!
