Arduino is a development environment, and a breakout board for micro-controllers. Most Arduino compatible boards use AVR microcontrollers. but there are ports of the development enviroment that work with PIC and MSP430 microcontrollers.
..I mention this, because it makes things really confusing if you actually try to use them beyond a breadboard.
