Where can I learn the absolute basics?

So I'm an absolute beginner :P obviously. But I mean completely absolute beginner, I don't get much of anything! I went through the "Start Here" section, but I still get confused on some things. I understand programming, I just don't get what everything is, what it does, why it's there, etc. and no one, literally no one, explains the sheer basics in their posts. So is there anywhere you can direct me for beginners where I can start off learning the basics, like what each pin does on a microcircuit, what they can be used for, etc.
