How a Preset Potentiometer Works

A preset potentiometer (trimpot) is a three-terminal variable resistor designed for "set and forget" adjustments. A resistive track is connected between two outer pins, and a movable wiper (center pin) slides along the track when turned with a screwdriver. By rotating the adjustment screw, you change the wiper's position, which varies the resistance between the wiper and each outer pin. This allows you to precisely set a voltage divider ratio, calibrate a sensor threshold, or fine-tune an amplifier's gain without needing a full-size panel-mount potentiometer. Unlike user-facing pots, presets are intended to be adjusted during assembly or calibration and then left in place.

Pinout & Wiring Guide

Pin	Label	Description
1	Terminal A	One end of the resistive track - connect to VCC or signal source
2	Wiper (W)	Variable output - connect to the circuit input or ADC pin
3	Terminal B	Other end of the resistive track - connect to GND or reference

As a Voltage Divider: Connect Pin 1 to VCC, Pin 3 to GND, and read the adjustable voltage from Pin 2 (Wiper). Turning the screw sweeps the output from 0V to VCC.

As a Variable Resistor (Rheostat): Connect Pin 2 (Wiper) to one of the outer pins (e.g., Pin 1) and use Pin 2 and Pin 3 as a two-terminal variable resistor with range 0-100KOhm.

Project Ideas

• Arduino Analog Input Calibration: Use the trimpot as a voltage divider to provide a tunable analog reference voltage to an Arduino ADC pin - perfect for setting sensor thresholds or testing analogRead() values.
• LED Brightness Control: Place the preset in series with a current-limiting resistor to fine-tune LED brightness during prototyping without swapping fixed resistors.
• Audio Amplifier Gain Setting: Integrate into the feedback loop of an op-amp circuit (e.g., LM386) to precisely set amplifier gain during assembly.
