Imagine the convenience, if we could control different devices at home/industry by using a single PC. Our project aims at the same and could be used to control the printer power, loads & other household electrical appliances. The circuit comprises decoder, inverter, latch & relay driver sections. To control these equipments we are using PC’s Parallel port. The program of controlling is written in C language. It is compiled using Turbo C compiler.
The project though a bit expensive, is very efficient in control of real world peripherals.
