## Description

Models an ideal potentiomer with internal connection to Gnd and Vss. The dial has a discrete number of positions which a create steps of Vdd/Positions. The output voltage is calculated as Vdd * ( Position / Positions). The maximumv voltage is Vdd * ( Positions -1 )/ Positons because Position = Positions rotates back to position = 0
 
To rotate the POT you use the mouse to drag the rotation dial or you can programmatically control the value through the **RotorWidget** interface.
