i button lock
Walt-
Here's a starting place showing some working code:

FWIW, you could do all your 1-wire stuff using just one Stamp I/O pin
(your 1-wire network might even like it better). By the time you
get through hanging LCDs, keypads, toasters etc. off your Stamp, you
may wish you had minimized your 1-wire I/O pin requirements.
