Hello there,

I have always been interested in robotics and am finally taking the plunge. This site has been very helpful. Although I have a long history of professional development/programming experience and some engineering knowledge, I have very little electronics knowledge.

I just finsihed reading the $50 first robot tutorial for the fifth time and plan on undertaking the project next week or so. However, I'm the kind of person who, even for a first attempt, likes to know WHY I'm doing something, and the one part that really threw me for a loop was the electronics. I can follow the schematics (or at least the simplified, colored-dots version), but can't figure out why he made those decisions...what caused him to decide to solder together A and B, and not C and D? Where does one begin to understand that sort of thing?

Thanks very much! I look forward to the experience.
Matt

it has a lot to do with the certain pins on the microcontroller. only certain pins can handle certain jobs like motor and sensor pins are different because they do different jobs.

Thanks for the quick reply!

Ahhhh, so with each microcontroller, there comes a diagram of which pins do what. That makes sense and clears a lot up for me. Thank you. So what you wire into the breadboard or whatnot has to correspond to the setup of the specific model.

read datasheets on electronic components, and read books on basic electronics. that will help

Thanks. I've been scouring the web for resources on basic electronics and think I've found a few good starting points.
