If you're looking for a Stamp that has a built-in analog to digital converter, you won't find one. It's possible to use an I/O pin to measure voltage (see w.emesystems.com (http:www.emesystems.com) ... use the "app-notes" link and look for the section on the RCTIME statement), but this is relatively slow ... like for measuring battery voltage). For fast analog sensing, most people use an external analog to digital converter chip.
