How do I wire the B20K to an Arduino analog input?
Connect the two outer pins to 5V and GND, and the middle pin (wiper) to an analog input such as A0. The voltage read on A0 changes as you turn the shaft.
What does the B in B20K mean?
The letter B indicates a linear taper, so the resistance changes evenly across the shaft rotation. A-taper potentiometers are logarithmic and are commonly used for audio volume.
