I like that idea for space savings (using smaller resistors).
Maybe I can scale each of my inputs to a more realistic voltage vs trying to get them all with one sized fits all voltage divider.
I don't think the Arduino is as accurate at lower voltages but will do some reading on it.
Thanks!

OK, you could use a 1meg and a 10K. That will divide to 5V (4.95).

Buy Chinese. Bury freedom.
If you need resolution either way, try 3volts. 5 volts is the max you should run the input pin.
Resolution works very well for me
