    Hi

    I would like to switch on some lights (24v DC) using my PC - i was
    thinking either serial \ parralell interface - or USB if that is possible.

    As far as i can see i just need some kind of relay attached to the port, and
    then send a signal to trip the relay. Is this right?

    What kind of relay do i need? (If possible, i want one where i'd send a
    signal and it would turn on, send a signal to turn it off - as opposed to
    one where i need to send a signal constantly to have the lights on). Please
    bear in mind i really dont know much about electronics.

    Also, would it be possible to detect on the PC whether the relay is on or
    off?

    Thanks

    There are a few ideas to hookup relays to the PC printer
    port shown here.
