    Welcome to the forums.

    Always start your own thread instead of posting onto the end of another -

    Are you committed to the use of the parallel port for the control? The old printer port has lost support and is generally not present in modern computers.

    Do you have a power supply for the relay? How did you come by the list of hardware?
