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.

I ordered this and it doesn't come with the nice looking knob. It is the same plain shaft as shown in the photo for the panel mount version.
But after you used the ISP to upload codes, you can't use serial port to upload. You need to upload bootloader before you use serial port to upload.
I think you mean"angle"sensor..unless this is used to detect heavenly beings.
Sorry, over 5V could be burn the board.
