The potentiometer module contains a 10kΩ potentiometer. A potentiometer is a resistive component with three terminals, whose resistance can be adjusted by rotating a knob. It can be used to adjust motor speed, LED brightness, and more.
The main component of this module is a potentiometer. A potentiometer is a resistive component with three terminals, whose resistance can be adjusted according to a certain variation rule. It usually consists of a resistive element and a movable wiper. Based on the principle of series resistance and voltage division, when the wiper moves along the resistive element, a resistance value with a certain relationship to the displacement is obtained at the output terminal, thereby outputting a value from the analog port. This module can be combined with other modules to build interesting projects, such as making a speed-adjustable toy car with a DC motor, or a dimmable desk lamp with an LED.

Parameter Description
The module is equipped with a blue LED light, and changes in its brightness indicate variations in the current analog output value.
The white area of the module serves as a reference area for contact with the metal beam.
It supports programming via the Arduino IDE and provides a runtime library to simplify the programming process.
It supports graphical programming with mBlock, making it suitable for users of all ages.
The RJ25 interface is adopted for convenient wiring.
Modular installation design ensures compatibility with Lego series products.
It is equipped with connectors that support most Arduino series main control boards.
