Go to Post If you're in the Chairman's Award just to win the Chairman's Award, you're doing it for all the wrong reasons. The award is there as a goal to strive for, but it shouldn't be the reason why you conduct yourself and reach out to your community and beyond the way you do. - Lil' Lavery [more]

There is another alternative you could use. On the I/O tab of the DS, when it is set to Compatible Mode, you will see Analog Input sliders. You could read these instead of an external potentiometer. In this case you would read the values on the robot using the WPI Robotics Library>>DriverStation>>Compatibility I/O>>WPI_DriverStationGet Analog Input.vi. Then you would scale it accordingly to drive your motor.
Would the analog input(like a potentiometer) then act as a joystick and the digital inputs act as buttons on the joystick vi's? That seems to be my understanding.
