I am trying to develop a system that will interface with a uC that measures battery cell voltages one at a time and records them for later recall. I am trying to figure out how my two leads would get connected to an ADC so that nothing gets fried.
Think of a standard multimeter with each lead on either side of a battery cell (approx 2.1v or so)
Any help wrapping my head around this would be wonderful. I've been searching for the last couple of days and the only references I've found about ADC have only a single input. Where does the other input (the common lead) go?
Thanks for any help!
