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. What does “P” mean? “P” is for “panel mount” in this product. This Grove – Rotary Angle Sensor is a sister version of original Grove – Rotary Angle Sensor
. They are identical except the Grove connecter is moved to the back so that you can easily use it as a neat and wire-free human interface device.
