Potentiometers: An Introduction and How to Use Them
Potentiometers, also known as pots, are variable resistors that allow users to adjust the amount of resistance in a circuit. They are commonly used in electronic devices such as audio equipment, lighting systems, and motor controllers. In this article, we will introduce the basics of potentiometers and provide a step-by-step guide on how to use them in your circuits. What is a Potentiometer? A potentiometer is a three-terminal device that consists of a resistive element, a sliding contact (wiper), and two end terminals. The resistive element can be made of materials such as carbon, wire wound, or conductive plastic, and its resistance is proportional to its length. The sliding contact…
