| 特長: | Description
An adjustable potentiometer can open up many interesting user interfaces. With this rotary potentiometer just turn the dial and the resistance changes. This potentiometer from Bourns has a 1/4" metal knurled shaft diameter， solder lug terminals， no detents， and has a 100K linear taper.
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! |
