PICs are an enabling technology. All those logic, control, communication and display functions that our projects need can be packed into a single chip--a chip that can be reconfigured at your pleasure. PIC development can be done with just a handful of parts: as EPROM eraser, some kind of programming language and a low-cost PIC programmer. Here are some "getting started in development" articles and some "just build what I did" articles.  Originally, a PIC was a programmable interface controller, but one can also see it defined as peripheral interface controller.

The Basic Stamp, Picaxe, and Arduino combine a processsor with rudimentary programming, so you don't have to spend as much time re-inventing the wheel and can concentrate on developing something new.
