The microcontroller is a single-chip microcomputer that integrates the main part of the microcomputer on a chip. With the development of technology, microcontrollers have become more and more powerful, which makes their applications ubiquitous and in various fields. For example, motor control, barcode reader/scanner, consumer electronics, gaming equipment, telephone, HVAC, building security and access control, industrial control and automation, and white goods (washing machine, microwave oven), etc.
