Overview A potentiometer is a device that can change its resistance by moving a contact along a fixed resistor. It has three terminals: one connected to each end of the resistor and one connected to the movable contact. By adjusting the position of the contact, the potentiometer can divide the input voltage into different output voltages [Read more in Wikipedia]. Potentiometers work by creating a voltage drop across the resistor that is proportional to its length. For example, if the input voltage is 10...
