Best potentiometer for an arm aplication

[Luan Motta]

Sorry, I was not very specific, but we need a 3V, 180 degrees, 10KΩ potentiometer.

We are programming the arm with a window motor in java. We are using the potentiometer as reference for the joystick. When the arm of the potentiometer is greater than joystick, the arm will decrease, and When lower, it will increase. Always watching the same degrees of the joystick.

If you guys recommend me a potentiometer that the voltage will go from 0V to 5V, it doesn't matter the voltage, but we would like to have a 3V.

I'll be grateful if someone pass me links to buy potentiometers.
