WH148 rotary potentiometer with 3 pins, 20K value, intended for applications where manual adjustment of a signal or voltage is required. The resistance variation follows a linear curve between minimum and maximum, making it suitable for smooth and predictable adjustments such as brightness control, motor speed control, or analog signal tuning.
The 6mm diameter metal shaft allows the installation of a standard knob, and the body features a threaded bushing for panel mounting.
The package includes the washer and nut needed for installation. The robust construction provides a service life of 10,000 rotations, and the 300-degree rotation angle offers good resolution across the full adjustment range.
The potentiometer is compatible with Arduino, STM32, ESP32 boards, or other platforms with analog inputs, and is often used as a voltage divider for reading a variable value through the ADC converter.

Usage:
Insert the potentiometer shaft through the hole in the panel and secure it with the included washer and nut.
Connect pin 1 to VCC and pin 3 to GND to use it as a voltage divider.
Connect pin 2 (the wiper) to an analog input of the development board, for example A0 on Arduino.
Rotate the shaft to vary the output voltage between 0V and the supply voltage.
Read the value through the ADC converter and use it in your desired application.
Avoid forcing the shaft beyond its mechanical limits to prevent damage to the resistive element.
