ADS1115 Gain & Calibration
#5
I did this project with an ESP32 and SensESP, but never got it installed before I sold the boat. I think the ADC reads voltage and assigns a digital value, does it not? So it isn't displaying a voltage, but 4.096 (2.048 or 1.028) as the max voltage, whatever that is? Would it not, then read 0 (.5 volts-ish - bottom range) to 4.098 (4.5 volts-ish - top range)? Test it with a potentiometer and see what it displays as min/max of known/equivalent voltages.

I've always had a hard time understanding how these things work, but usually muddle through to make it happen. I am probably way off here.
