The potentiometer twig produces analog output between 0 and Vcc (5V DC with Seeeduino) on its D1 connector. The D2 connector is not used. The angular range is 300 degrees with a linear change in value. The resistance value is 10k ohms, perfect for Arduino use. This may also be known as a rotary angle sensor.
Potentiometer is one of the most useful basic components. This is a 10k dial type potentiometer with knob. It’s space-saving and user-friendly. You can read the actual resistance value via the straightforward knob without auxiliary instrument like multimeter. Each has been pre-calibrated. You can implement it into your circuit right out of the box.
