To control 2 rotatory potentiometers with myDAQ and LabVIEW, we mount on our breadboard the schematic reported in the next figure and we connect it with myDAQ.
We have to use only one DAQ Assistant VI with two voltage input like reported in the last figure (but not two DAQ Assistant because this procedure causes an error type “The specified resource is reserved…”). We will use both the ai0 and ai1 analog channels on myDAQ.
Values that we will read inside the Numerical indicators will be between 0 and 5V. Before these VI we have to use Split Signals to split signal into two values.
