Hello there, I have the BS2 & BS2px boards, I need to make a diesel level detector(for·trailer tank), I think don't need a RC circuit cause the tank output is energized, it uses a 240 ohm potentiometer, I need to read the voltage output and tried with BS2px but only read with one comparator, I have tried to activate the other ports like comparators and no success and only 5V like maximum to compare(maximum voltage output=8VDC, minimum is 3VDC), any help welcome, thanks in advance.

    Download the Basic Analog and Digital tutorial from the Parallax Stamps in Class webpage. It'll show you how to use external analog to digital converters. Also check out Tracy Allen's website www.emesystems.com/BS2rct.htm. The battery monitoring using RCTIME is a way to read voltages with a Stamp and a few passive components.
