8 CHANNEL DEVICE CONTROL USING PC PARLLEL PORT

PROJECT DESCRIPTION

This project describes a new economical solution of home light control systems. The presented home light control system can be used for different sophisticated home applications. The control system consists of a PC, and control circuitry and the electrical devices.

The intelligent control software, which has been developed using high level graphical programming language (Visual Basic). A complete solution of a home control system is presented in this project. The home lights was fully controlled by the PC and the commands from the PC was done by the control circuit with help of the relays.
