A basic Arduino Circuit and Code Setup containing A Servo motor along with a Potentiometer. The aim is to control the position of the motor according to the Value of potentiometer.

Upload the code to your Arduino board using the Arduino IDE. Open the Serial Monitor to view the potentiometer value and LED brightness. Adjust the potentiometer to see the LED brightness change ...

We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan.
