Potentiometer use in Labview

[Doug Norman]

Have you looked in the Example Finder? There is a Potentiometer with Driver Station example. It's not for the robot side of things, but it does show a potentiometer - the wiring idea is the same. I'll look into adding a robot side potentiometer example to the Example Finder.

I have a simple example of the basic code side on this page about a quarter of the way down, labeled Analog Input example.
But what you're looking for is probably the PID Example close to the bottom.

That demonstrates the use of a steering potentiometer to position a motor based on the position of a joystick.
For your fixed position arm you'd replace the whole joystick input with just a constant = the exact voltage you'd want the arm potentiometer to read when the arm is where in a fixed position.

You'd have to add a case statement to chose the different values you want the pot to have.

Its pretty easy once you get started, the starting from the example Mark posted, the Analog get returns the value of the potentiometer as a voltage, you can start making this.

You should change the .5 to whatever value you want the motor to run at, and the 2.4 and 2.5 to where you want the motor to stop at which value on the potentiometer, you should also change the way this is done once you get used to PID controls, as this is a really mediocre way to code this, but it works as a proof of concept.

Thank you all very much, u helped me a lot
