Low Voltage Sense

I am wanting to program the stamp to make an output signal go high if an input pin somehow senses a voltage threshold. Specifically if a voltage drops below 10 volts the stamp will make a pin high. Can anyone help with circuit and code. Thanks very much!

    You could make a voltage divider, perhaps using a 10K or 100K trimmer pot which could be adjusted to the HIGH/LOW threshold of the BASIC Stamp input pins.· That would be simpler, but if you need more accuracy you could use a comparator.
