# Potentiometer Module
## **Principle**
The Potentiometer Module is a component that adjusts resistance values based on a defined pattern. It operates by sliding a brush along a resistive element, outputting a voltage that maintains a specific relationship with the input voltage in the circuit.

The potentiometer module can be connected to the P0, P1, or P2 ports of the **micro: bit smart hub**. In the coding environment, the analog values from the potentiometer module can be read. Its characteristics are as follows:
+ **Clockwise rotation**: The output value of the potentiometer decreases.
+ **Counterclockwise rotation**: The output value of the potentiometer increases.
## **Modular Coding**
In the MakeCode coding software, the sensor signal value from the P0 port can be read using the Microbit extension. The data can then be visualized on the micro: bit's LED matrix.
