Re: Potentiometer use in Labview

A properly wired potentiometer provides a variable voltage that is proportional to the angle at which it is turned. Voltages are analog signals, and get connected to the Analog Breakout.

Each set of three pins on the Analog Breakout provides exactly what you need to connect to a potentiometer. Wire one end of the pot to the +5 pin (center). Wire the other end of the pot to the Ground pin. The Signal pin goes to the wiper of the pot. Usually, the wiper is the middle one of three connections on the pot. On a typical PWM cable, Ground is black, +5 is red, and Signal is white.

Read the value using an Analog Get function.
