I know you guys are just dying for more information about microcontrollers. Well, I've just so happen to come across this presentation on the internet (I'm seeing some potential in this...).
This guy will tell you everything that you want to know about microcontrollers and more (probably WAY more). It's a good presentation regardless of your existing knowledge of the subject. If you'd like, you can just listen to parts of it , there are bookmarks on the left side so you can jump to different sections to get some overviews.
Check out the link here.
But more importantly, check out that guy's voice! It's like SILK! I'd listen to him describe the procession of an episode of food poisoning. Which is probably a good thing since, for some of you, this presentation will be equivocal to such a description.
