Potentiometer
$2.16A potentiometer is a manually adjustable variable resistor with 3 terminals. Two of the terminals are connected to the opposite ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. The potentiometer essentially functions as a variable resistance divider. The resistive element can be seen as two resistors in series (the total potentiometer resistance), where the wiper position determines the resistance ratio of the first resistor to the second resistor. If a reference voltage is applied across the end terminals, the position of the wiper determines the output voltage of the potentiometer.

Potentiometer Module for Arduino
$3.24A potentiometer module for Arduino is an electronic component that allows for the measurement of analog values by converting the position of a rotating shaft or slider into a electrical signal. Potentiometers are commonly used to control the brightness of a light, the volume of an audio system, or to sense the position of a joystick, among other applications.
A potentiometer module for Arduino is a convenient and easy-to-use component that is specifically designed to be used with the popular open-source electronics platform. The module typically contains a potentiometer, which is a variable resistor, as well as a few other electronic components that allow it to interface with the Arduino board.
