General Description of Microcontrollers

A general explanation of the uses and applications of microcontrollers. Microcontrollers can be used to: sense the environment using sensors, control other components with general purpose output pins, convert analog voltages to digital as a range of numbers and output analog like voltages using PWM (pulse width modulation). With these features, microcontrollers are used all around us, in things around the home, robots, machines, etc.
