My load cell unfortunately starts at a negative voltage (-8 to 0 volts depending on amplifier gain). I dont believe the Arduino UNO will read negative voltages (i just get a value of 0). My issue is compunded by the fact that when force is applied the voltage goes ABOVE 0 (up to +8v depending on amp…

Analog reading negative voltage...
