    Hi Dave, nice project.I am well down the physical production of the hardware connections. Can you advise me as to why you have 10k resistors in series with the micro switch for both open and shut switches. I have read in other places where they should be pull-up resistors to +5volts. Cheers John aka robbotherobot
