      So I switched the cap over to the sensor input side of the voltage divider(Thx MarkT), and re-adjusted the slope calculation for the new voltage drop, and with a little tweaking of slope, I am now getting steady and fairly accurate readings. THX...

      yep, the regulated 3.3v, not 5v. I will get rid of the 4k7. My voltage divider circuit is similar to above, but without the diodes. I thought the cap (mine is a 10nf) went from the divided resistors to ground? not the input signal to ground...

      thx for replies! I read about the diode setup. I just don't have any on hand and was wondering about other options via code. I will give the diodes a try. Something like this? THX!

      I have a 5v output analog pressure sensor. It does not output > 3.3V until 70psi. My system does not go over 60psi. BUT, just in case I do exceed 70psi, I was thinking that : if (psi <= 69) { analogRead (sensorPin);} if (psi>=70){...
