Re: Sharp GP2D02 code available 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?
