Is there any way to measure a resistance using the basic stamp, almost as if it
was a digital multimeter?

    You could set up a "timebase" by using the D.U.T., to charge a capacitor,
    and use the stamp to monitor how long it took to charge. Mathematically,
    you could then find the resistance.

    Yes, there is a command called RCTIME and it will measure an unknown
    resistance. I am almost sure there is a tutorial you can download that will give
    you
    the code and the hardware set up example.
