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.
