Home automation project>>
Title : Home Automation
Objective : This project is an attempt to handle the home appliances like fan,
Bulbs, Tubes & Television with the help of computer system via
Printer Port.
Team Size : one
Period : October 2002 to November 2002
Technical Detail :
Power Supply Dual (5V regulated for circuit and 220V for home appliances)
PCB All purpose pre drilled PCB
Body Card Board (I used a plastic box.)
Expression :
my circuit board of home automation project.
Cost of the project: Around 400 Rs(5 $).
Components used:
Parallel male port
Relay (6 volt)
Resistor (1 k ohm)
Transistor (IN 2222)
Zener diode (IN 4148)
Wire belt
Bread board
Circuit Diagram:
Coding and working:
The simple code for just taking the output from the printer port is Given below .
#include<conio.h>
#include<stdio.h>
void main()
{
outportb(0x378,4);
}
0x378: it is the address of the printer port. And usually it is same for all computers.
This, the simple code for just taking the o/p from the printer port but if u want to take a good programming and a good interface to provide a good interaction with the user, than move to either visual basic or visual C++ and call the above code and improve the functionalities like add timer by which the appliances are itself on or off according to the time.
to control it via computer we have to take a male printer port or the wire lead of any printer and for the more detail of Connection via printer port click here: Printerport
Future Prospects:
If time allows I would like to do it wirelessly.
