Potentiometers adjust the voltage level sent to Arduino analog pins by adjusting

Potentiometers adjust the voltage level sent to Arduino analog pins by adjusting their position. Resistance tracks and sliding contacts make up voltage dividers. An Arduino analog input reads the voltage output from potentiometer knobs turned by the user. In interactive projects, users can control LED brightness, motor speed, or servo position with this interface. With potentiometers, users can input data in an Arduino-based application in a simple, intuitive manner. Potentiometers are also used to adjust the volume of audio devices and other electronic components. They are a cost-effective way of providing a user-friendly input interface for Arduino projects.
