I'd just like to apologize in advance for asking this, I understand that it's probably been asked many times but I couldn't find an answer exactly applicable to me. Anyway, I want to buy a microcontroller kit, and am unsure which one to buy. I am going for my masters in computer science so the programming aspect of it doesn't bother me (ie. I'm willing to program in assembly). Also, I borrowed my friends basic stamp to see what it's like and I finished all the projects in about two weeks. It was way to simplistic. Additionally, I hated their "P-basic". I've been looking at buying the arduino but I've heard similar complaints about it (that's it's overly simplistic). Is there a good microcontroller kit that I can buy, that isn't catering to people with no background at all? I would really like to understand circuits and electronics at a deeper level, but these kits don't seem to allow that. Also, I am on a budget, so it would be great if I would be able to use the microcontroller in the future as I get more advanced (although, I am willing to spend money for a short term kit, if necessary). Does something like that exist, or am I being too picky?
