So you want to get a microcontroller to do this, what is it you're trying to do? There may be a simpler way we can recommend so you don't have to buy a microcontroller.

If you do need a microprocessor there are LOADS to choose from. The Arduino environment is quite easy to use and has loads of documentation. www.arduino.cc
