I'm attempting to get a better handle on how the ADC works exactly. How would the ADC operate in comparison from A to B
A) using a 5vdc board with 7.4 to 8.5vdc as a power supply and being regulated to 5vdc
B) using a 5vdc board with 3.7 to 4.2 vdc supplied after the regulator (no voltage regulator)
if one were to use the formula to convert 1023 to 5vdc, would 613 be 3vdc? or is the vcc voltage a refference point to the 1023?
