The Okdo analog potentiometer is tantamount to a 0∼10KΩ resistor. When you rotate the potentiometer, its resistance will alter. Then we can set up the corresponding circuit, convert the resistance changes into the voltage changes. These voltage changes will be transmitted to GPIO port, producing the analog signals in the range of 0-3.3V.

Compatible with RJ11 6P6C OKdo TelePort Control boards and expansion shields
Use this potentiometer to detect the rotation position of the knob
Ideal for use cases like volume control, speed control or selecting an item on a display

For use with micro:bit, please order the Okdo BBC Micro:bit Expansion Board

For use with Arduino, please order the Okdo Control Board for Arduino
