actuator
Something that influences a quantity in the environment to a degree controllable by an electrical signal. Actuators exist that move things, illuminate things, etc..
The general actuator circuit appears below.
Here it is assumed that there is a Device that is set up to provide the control signal to the Actuator. The device provides 5V or +V and 0V in addition to the actuator to provide power. Most actuators can be thought of in this way - as requiring power and a control signal and delivering some kind of influence to the outside world.
