Potentiometer and It’s working
A potentiometer is a crucial three-terminal resistor featuring a sliding or rotating contact that forms an adjustable voltage divider. When using only two terminals (one end and the wiper), it functions as a variable resistor or rheostat. The potentiometer’s three pins consist of two connected to the resistive element (blue and green) and one connected to the adjustable wiper (black). The potentiometer can serve as a rheostat to vary resistance or as a voltage divider. The position of the wiper determines the amount of resistance imposed on the circuit, as demonstrated in the figure below.
