Arduino Analog Inputs:

  1. Disconnect the Arduino Analog Input from the Device Analog Output
  2. Connect the Device Analog Output to a voltmeter
  3. Verify the Device Analog Output works based on reading from the voltmeter
  4. Reconnect the Device Analog Output to the Arduino Analog Input
  5. Verify with a voltmeter the voltage at the Arduino Analog Input to ensure the device is still working as expected.
  6. Begin to troubleshoot the analog reading in your arduino sketch.
