    Can I get my computer to put out a small electrical current? (act as a switch)

    I'm wondering if I can write a program/interface in VB to send a signal or small electrical current out of my box? Say I wanted to turn on a low watt light bulb or diode? What kind of output device/line would be used?

    Could also go Old School and just use the Serial or LPT ports. You can get 3-5 V but the amperage is low so don't expect much. Also, I hope you either know what your doing or are playing with junk cause you can burn the diodes up in a LPT, COM or USB port rather easily by drawing to much current.
