Product description: DS1841 - Digital potentiometer 10K I2C STEMMA QT/Qwiic - Adafruit 4570.
The Adafruitdigitalpotentiometer allows you to adjust the circuit without having to turn the knob manually. A module with anI2Cinterface in which the resistance dependence on the slider is logarithmic. Potentiometer with a resistanceof 22 kΩ to 3.7 kΩ and128 hook points.Logarithmic type devices are used for volume control as they better match the human ear's response to sound.
