my team made a control box using the Labview LVH-LINX library (you can see more about them in
this link )
we planted the code to read the data from the arduino (we used the UNO ) in our dashboard, sanding the data to the robot using the SmartDashbord VI's
i think that the same method will allow you to set outputs to an arduino...
