The Potentiometer Module is a tool used to convert voltage into analog values for use in many scenarios. The potentiometer serves like a rheostat, changing the resistance by turning the shaft and allowing voltage to be divided and read from a signal pin. The received voltage value is passed through a signal pin and converted to an analog value in the range of \[0, 255]. Thus, this value can be used in different ways in robotic systems.
The potentiometer module can be used in systems needed to adjust different levels of function such as LED brightness level, volume level or motor speed control.
