Shop Potentiometers & Trimpots by Type

Our potentiometer and trimpot range may include products such as:

• Rotary Potentiometers: Adjustable resistors used for knobs, volume controls, analog inputs, speed control and user adjustments.
• Trimpots: Small trim potentiometers used for calibration, fine adjustment and circuit tuning.
• Preset Potentiometers: Board-mounted adjustable resistors used to set values inside a circuit or module.
• Linear Potentiometers: Potentiometers with a linear resistance change suitable for many control and measurement projects.
• Potentiometer Modules: Pre-assembled potentiometer boards used for Arduino, ESP32 and electronics prototyping.

Potentiometers for Arduino, ESP32 & Electronics Projects

Potentiometers are commonly used with Arduino compatible boards, ESP32, ESP8266, Raspberry Pi compatible boards, audio modules, motor controllers, LED dimmers, sensor circuits and analog input projects. They allow a circuit or microcontroller to read a variable position or adjustable voltage.

Always check resistance value, taper type, power rating, shaft type, mounting style, pinout, physical size and whether the potentiometer suits your circuit before ordering. For microcontroller analog inputs, the potentiometer is often wired as a voltage divider.

Rotary Potentiometers, Trim Pots & Adjustable Resistors

Rotary potentiometers are useful where the user needs regular adjustment, such as volume, brightness, speed or menu control. Trimpots are better for internal calibration or setup adjustments that do not need to be changed often.

Frequently Asked Questions

What is a potentiometer used for?

A potentiometer is used as an adjustable resistor or voltage divider. It is commonly used for volume controls, brightness control, speed adjustment, analog inputs and circuit tuning.

What is the difference between a potentiometer and a trimpot?

A potentiometer is usually designed for regular user adjustment with a knob or shaft. A trimpot is a smaller trim potentiometer usually used for internal calibration or occasional adjustment.

Can I use a potentiometer with Arduino or ESP32?

Yes. Potentiometers are commonly used with Arduino, ESP32 and other microcontrollers as analog input controls when wired correctly as a voltage divider.

What should I check before buying a potentiometer?

Check the resistance value, taper type, shaft style, mounting type, power rating, pinout and physical size before ordering.

Can you help me choose the right potentiometer or trimpot?

Yes. If you are unsure which part suits your project, contact AuscomTech with your circuit voltage, required resistance value, mounting style, adjustment type and any existing part markings.
