The ADC on the esp2866 12E is only able to read 0 to 1 volt. So i have a divider that scales the 3.3 volt to 1 volt on the input but my reading are way off
Im getting 180 with adc.read and it's .227 on the pin and .505 at the tmp36 so if I change to volts the 180 it doesn't scale to .505 volts. That the tmp36 is showing
I'm .075 off of a real reading.
