I just finished sending a question to the mail list but may have my
problem fixed? Just from blind luck.
I have digital out #7no the expansion board and digital in#15 on the main
board and the first of the zeros on on the LCD changes to a one at about
a 10 inch range. Whoopee, what's the other zero for? Have I got it right?
Ha, "Even a blind squirrel finda a acorn enery now and then"
