    Thanks for posting this, Jon.· It will be very useful for me.

    I'm a little confused about V3 and V4 with the pin voltage drop.· What is that value?

    Thanks,

    Chris Isaacson

    Some micros have a small voltage drop on their output pins; I measured the BASIC Stamp and it's negligible -- (0.01).
