Project Description :

The PC parallel port is a powerful platform, though inexpensive, for implementing projects dealing with the control of real-world peripherals. It can be used to control the printer as well as household and other electrical appliances.

 

The computer program included as part of the project controls relays through the interface circuit, which, in turn, switch the appliances ‘on’ or ‘off’. The parallel port has 12 outputs including 8 data lines and 4 control lines.

 

            The hardware circuit developed can be used to control up to 255 electrical appliances using only 8 data output lines from the parallel port. Besides, the software program allows the users to know the current status of the devices.
