Home automation system using parallel port / Muhamad Syahrizam Salidin

The main purpose of this project is to help users how to control their electrical
appliances while they are not at home through the control timer. This project focused on
the developing home automation system in Windows platform. The home apphances can
be controlled through parallel port on Personal Computer (PC) by program developed
using software for example Microsoft Visual Basic. The home appliances and the PC
can be accessed and controlled via parallel port cable by a Home Automation System
program. Parallel port interface circuit was constructed for the purpose of the controlling
the appliances. Basically the parallel port is to be used as a media inter&ce in this
controlling purpose. The parallel port is a very simple and affordable technique in
controlling external circuitry. With just a D-Type 25 Pin Male Connector, buffers, relays
and simple wiring, the computer can be interfaced to the external devices.
