    I see. So the POT and RCTIME are useful if your pic doesn't have an a/d convertor.

    Thanks for the info on the circuit, using a resistor before the pin and the cap for filtering. I appreciate it.

    I'm looking in one of the books for A/D conversion. They show a 50K pot, the wiper going directly into the pic pin, but there is a 15K "pull-up" resistor connected from the +5V to the pot. Is this recommended?
