This is a very easy and fun to build project that will allow you to control up to eight external devices through your
computer's parallel port. You may for instance control different appliances such as lamps, computers, printers, tv sets, MP3 Players
radios, music systems, air conditioners, air fans, garden sprinklers and anything else you can think of, all through your PC Circuits
computer. You can do a simple test by connecting a LED directly to a ground and any PINs 2 through 9 of your parallel
port. The voltage on the parallel connectors is around but it drops to around 2V once you connect the LED. You PCB
may use a 100 Ohm r
