Digital PotentiometersDigital potentiometers are a type of electronic device that is used to adjust the resistance of a circuit. These devices are commonly used in applications where a variable resistance is needed, such as in volume control or brightness control circuits. Digital potentiometers are often used in place of traditional mechanical potentiometers, which use a physical knob or dial to adjust the resistance. Digital potentiometers offer a number of advantages over mechanical potentiometers, including more precise control, higher reliability, and the ability to be controlled digitally. They are often integrated into larger electronic systems, and can be controlled by a microcontroller or other type of digital control device.
