The PICAXE-08M microcontroller chip supports 5 input/outputs including 3 analogue inputs. Great for simple projects or as an auxiliary controller for a larger robot.
PICAXE is a neat entry-level microcontroller system that is relatively cheap to get started with. The chip is programmed with a simple serial connection and the BASIC development environment is free! PICAXE has some excellent educational applications and support, and is a great entryway into more complicated embedded systems. If you're look for a place to start with microcontrollers, PICAXE is a great way to go!
