Procedure
- 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.
Challenges
- 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.
