Paver steering potentiometer

Photocoupler

A potentiometer (English: Potentiometer) is a type of variable resistor. It is usually composed of a resistor body and a rotating or sliding system, that is, a moving contact is moved on the resistor body to obtain a partial voltage output. The role of the potentiometer - adjust the voltage (including DC voltage and signal voltage) and the magnitude of the current.

The structural characteristics of the potentiometer - the resistor body of the potentiometer has two fixed ends. By manually adjusting the rotating shaft or the sliding handle, changing the position of the moving contact on the resistor body changes the moving contact between any fixed end and the fixed end. The resistance value, which changes the magnitude of the voltage and current.
