Make has a link to an article about what to look for in a microcontroller. Microcontrollers, just a few years ago, seemed exotic and high-tech; now they are so cheap, and so powerful, that plain old analog circuitry hardly seems to make sense. Why tinker with dozens of discrete components when you can just wire your peripherals onto what is effectively a single-chip computer and then throw a bunch of software at the problem? Ahh, what a world.
