this code is one night old. more to come from it but it’s not much now:

#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(2, 3, 4, 5, 6, 7);
/*
brb 20091121
control 2 x10 devices (4 &2) via momentary switches on pins 10
and 12. x10 interface on pins 8 and 9 and a 16×2 lcd on 2, 3,
4, 5, 6, & 7. messages will be printed to the serial console and
to the lcd screen

hold down both buttons to shut all units off
