Computer control is using a computer to control the action or movement of an object.

How does Computer Control Work?

  1. An input device transfers information from the outside world into the computer. Sensors are input devices because they measure different conditions.
  2. Computers will process the information entered from different input devices using a control program.
  3. A control program will respond by controlling devices called actuators:
Actuator Action Produced
Bulb Lights up an area.
Motor Rotates a shaft.
Buzzer Makes a beeping sound.
Heater Produces heat.
LCD Display Displays a graphic.

An interface (sometimes called a control box) is usually used to connect many input devices and actuators to a computer.
