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