#### Fabiano Nunes

I would like to know the cheapest way of how to turn on the lights of my house using my PC!!
I need a network? I need to develop my own program to do that? Which is the easiest way to do that??

Thank you

For about $200 US you can get a graphical user interface, a board-style PLC preprogrammed to communicate with the PC from Advanced Monitoring Technologies ( www.amt.nb.ca ). contact me directly at [email protected] for my own uses of the system. A #### Archie Jacobs The cheapest way would be to use an I/O module with 5VDC input and 120VAC output, such as an Opto22 part # G4OAC5, and use the data lines from the paralell port to turn it on and off. You can write a program in any language to send values to the paralell port with print commands. I have used entrelec part # 10 131.14 to do this to control a valve on the plant floor, but the entrelec requires a 24VDC power supply. This will run you in hardware costs all of about$15 per light.
