Microcontrollers are is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications. Microcontrollers are useful for controlling open source hardware projects and tools like the RepRap 3-D printer.
