A digital potentiometer that lets you control a voltage divider with serial signals from your microcontroller. Wire it up like a standard potentiometer, then use digital commands to adjust the wiper position — no mechanical knob required.
Because the wiper is software-controlled, you're not locked into a fixed sweep profile. Write your code to produce linear, logarithmic, or any custom response curve. Digital potentiometers also pair well with rotary encoders, allowing you to consolidate large banks of pots into a single smart rotary control.
Key Features
- 10 kΩ Resistance – Standard value for a wide range of applications
- Serial Interface – Control wiper position digitally from any microcontroller
- Custom Sweep Profiles – Linear, logarithmic, or any curve you program
- No Mechanical Wear – Solid-state design for long-term reliability
Ideal For
- Digitally controlled audio volume and tone
- Adjustable LED brightness and lighting control
- Sensor calibration and tuning
- Replacing mechanical potentiometers in automated systems

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
