Rotary Linear Taper POT with 3 Straight Pins
Linear taper potentiometers, informally called B type, are normally applied for voltage control. They are used when the division ratio of the potentiometer must be proportional to the angle of shaft rotation.
An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC on a microcontroller and get a variable input from the user!
