For example, a light dimmer uses a potentiometer to control the switching of a TRIAC and so indirectly to control the brightness of lamps. Preset potentiometers are widely used throughout electronics wherever adjustments must be made during manufacturing or servicing. See more A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. See more Potentiometers consist of a resistive element, a sliding contact (wiper) that moves along the element, making good electrical contact with one part of it, electrical terminals … See more A digital potentiometer (often called digipot) is an electronic component that mimics the functions of analog potentiometers. Through digital input signals, the … See more Potentiometers are rarely used to directly control significant amounts of power (more than a watt or so). Instead they are used to adjust the level of analog signals (for example volume controls audio equipment), and as control inputs for electronic circuits. … See more Some terms in the electronics industry used to describe certain types of potentiometers are: • Slide pot or slider pot: a potentiometer that is adjusted by … See more The most common way to vary the resistance in a circuit continuously is to use a rheostat. It is basically used to adjust magnitude of current in a circuit by changing length. … See more A membrane potentiometer uses a conductive membrane that is deformed by a sliding element to contact a resistor voltage divider. … See more WebLet's learn how to read a potentiometer using Arduino's analog input!
