The division should use 1023.0 to get the correct voltage range.

No. It's funny, I noticed that it was correct in the posted mess of code and thought at least she got that right!

Dividing by 1023 or 1024? The final verdict on analogRead

The correct answer is: 1024 (but the error is so small if you use 1023, it actually doesn't matter since the reference volt will vary with a much larger margin of error than your calculation will introduce). But in case you are still wondering why not 1023, here it is. After reading many responses from many posts on this exact issue (and some go into very technical detail why it should be one or the other), the bottom line is this: The confusion boils down to a simple miss interpretation of t…

The difference is minimal so I don't usually bother pointing it out when 1023 is used.
