01 Simple Circuits How to use a Potentiometer Working Principle and Circuit Diagram \$\begingroup\$ A potentiometer can indeed regulate voltage. Or, rather, it can represent the input part of the closed loop for voltage control. A voltage meter provides the output, and a human operator turning the knob or moving the slider provides the control. \$\endgroup\$ - Set up the Voltage Divider. Remember to GROUND the potentiometer. Forgetting to ground the POT seems to be the common mistake. 3.) Place the LED and current limiting resistor on the board. Basic Red LEDs - This is a very basic 5mm LED with a red lens. It has a typical forward voltage of 2.0V and a . rated forward current of 20mA. Features:
A potentiometer is a three-terminal variable resistor that allows for adjustable voltage division in an electrical circuit.It functions by varying the resistance along its length, providing a way to control the output voltage. The main components of a potentiometer include the resistor body, wiper, and terminals.

Wiring Example #3: Potentiometer as Volume Control This example uses all three pins of the potentiometer to create a simple way of adjusting the volume of an audio amplifier . By connecting it like this, you'll get a voltage divider that decreases the voltage of the input signal.
The output voltage will be taken across any one of the two input terminals and the sliding contact. The POT helps us to use variable voltages in the same device. Different Types of Potentiometers. The Potentiometer or POT is manufactured by using different types of materials like carbon composition, cermet, metal film, and conductive plastic.
