About this product
The WH148 is a 50KΩ single-turn rotary potentiometer with a linear taper, supplied with a knob on a 6mm knurled metal shaft. It is used to adjust voltage or signal levels manually in electronic circuits, including volume and level controls. The three-pin layout wires directly to an Arduino analog input, and the threaded bushing allows panel mounting.

Frequently asked questions
How do I wire this potentiometer to an Arduino?
Connect the two outer pins to 5V and GND, and the center wiper pin to an analog input such as A0. The analog reading changes as you turn the knob.
Can I use it to set a voltage between 0 V and 5 V?
Yes. Connect the outer pins across the supply and take the output from the center pin. The output voltage varies proportionally with shaft position between the two supply levels.
