I am using an Arduino Uno along with a datalogger shield. The device that I have to connect it to has two outputs: +10V and -10V and I guess the difference in that is what I need to record.
At first I was told that it was only going to be a single output of 0-10V so I made a simple voltage divider to get a single-ended output of 0 to 5V so that the ADC could read those values safely. But now that I know that that's not the case, I'm a little confused as to how to move forward with this.
Please advise on how I can tackle this situation. I know the arduino doesn't deal with negative voltages. My knowledge is very limited electronically/electrically so I'd appreciate any help I can get!
