What is a micro-controller?

A microcontroller is a compact integrated circuit that receives input from the environment, processes the input, then produces an output. It receives input from its I/O pins and processes the signals received using the CPU onboard the chip. Microcontrollers are usually embedded in larger systems and are utilized in many areas of life including vehicles, medical devices, home appliances, and more.
