• Open the LINX - Analog Read 1 Channel example from the LabVIEW Example Finder.
  
  
• Select the AI channel 13 which is connected to the onboard potentiometer.
  
  
• Add a Write To Spreadsheet File VI after the while loop.
  
  
• Connect the Analog Read output to the Write To Spreadsheet file 1D array input.
  • Change the while loop tunnel to Auto Indexing.
    
    
• Run the VI, and rotate the potentiometer.
  
  
• Click the stop button.
  
  
• Use the dialog box to save the AI data.
  
  
• Open the log file to see the data in spreadsheet format.

• Modify the code to create a 2D array where the first column is a AI sample and the second is a the time since the first sample in ms.
