A potentiometer is a simple knob that provides a variable resistance, which we can read into the Arduino board as an analog value. In this example, that value controls the rate at which an LED blinks. We connect three wires to the Arduino board. The first goes to ground from one of the outer pins of the potentiometer.

Rotary potentiometer also called rotary angle sensor is used to manually adjust the value of something e. The output voltage is in direct proportion to the rotated angle of the shaft. Arduino's pin A0 to A5 can work as analog input. The analog input pin converts the voltage between 0v and VCC into integer values between 0 and , called ADC value or analog value. By connecting an output pin of the potentiometer to an analog input pin, we can read the analog value from the pin, and then converts it to a meaningful value. After getting the integer value from the analog input pin, we rescale this value into another value. Let's see the use cases.
