This document discusses different types of control devices, including actuators, motors, buzzers, lights, and heaters. Actuators are transducers that receive signals from computers and convert them into motion, such as operating motors, pumps, switches, and valves. Actuators are commonly used in appliances like washing machines and to control industrial robot arms and computer components like fans and disk drives. Buzzers, lights, and heaters can be turned on or off by actuators connected to switches.
