A Microcontroller is a Microcomputer in a single Chip. That means that a microcontroller chip
includes a microprocessor (CPU) as well as some often used peripherals. A controller is
used to control (makes sense!) some process or aspect of the environment. A typical
microcontroller application is the monitoring of my house. As the temperature rises, the
controller causes the windows to open. If the temperature goes above a certain threshold,
the air conditioner is activated.
