This project demonstrates how to use a potentiometer as an input device to control the position of a servo motor with an Arduino Uno. Turning the potentiometer adjusts the servo angle in real time, ...

- The potentiometer value (0–1023) is read via analog input. - This value is mapped to an angle (0–180°). - The servo rotates to the corresponding angle. - Serial output shows the raw value and mapped ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...
