Microcontrollers are enormously powerful devices that come in a very small – tiny, actually – package. Microcontrollers are essentially an entire computer contained on one chip. Microcontrollers have inputs and outputs, processors and memory and can be programmed to carry out specific functions.
Microcontrollers are utilized in many different applications. They are so inexpensive that they make ideal solutions to many different complex problems. They are highly utilized in the industrial world, where many automated processes depend upon microcontrollers to coordinate them. Microcontrollers are present on everything from the largest industrial machinery to the vehicles that people drive on the roads every single day.
