Trying to detect voltage differences, probably on the magnitude of nanovolts or possibly picovolts. I don't need to read the actual voltage, just detect the occurence of a change. The goal is to detect changes induced in an coil around a magnet... any insight on that would be helpful too.
Pretty new to most circuitry, but from what I've read a comparator or open-loop op amp (?) may do the trick. I'll ultimately be using arduino uno to do the detection.
Thanks!
