I'm sure details depend on these factors, but I'm not really talking about specific projects at this point. I just can't seem to find anywhere to even start. All I'm interested in at this time is *possibly* working toward a very simple project, something like lighting an external LED by clicking something...a starting point from where I can decide if I even want to go further with it. It's mainly the basic concept that I find interesting, but I'm not sure whether it's something I want to get into.

Thanks for the links, I'll check those out soon.
