This question already has an answer here:
Hope all is well.
I need the arduino UNO to read negative voltages, and I am worried that it might destroy the arduino.
What I am trying to do with the Arduino is to be able to read voltages from two of its analog inputs, then graph them in Labview.
The arduino will read voltages that makes the above graph.
If UNO can't do negative voltages, are there any other arduino model that is capable of reading negative voltages?
If it can't read negative voltage, do you guys have any suggestion how to make this happen? Because OPAMP inverter won't solve this issue.
Thanks a lot.
