Thankyou admin for your fast reply ,, well i weill use a modem, a pic , and ofcourse i will need interface between them, ,, what i am asking is where i can find information that will help me in doing this project,, and if there is anything you can give me advice on , i will be thankful.
1) First arrange a PC and Ensure that it has parallel Port. Not Laptop. Ok. PC. New PC will have slots. You can connect a parallel port in slot. If the Slot is not there, you can connect an External one for 7$.
2) Install .Net 2010, if your operating system is Vista 32bit/64 bit or Win7. Else install .Net 2008 for Xp (Sp2 is mandatory)
3) Now parallel port has 8 data pins, 5 control pins. So in a simple way you can control 13 devices efficiently.
4) Hardware Setup.
A relay 6v,Optocoupler, 230 v, and As electrical Engineer you must be knowing how to control the bulb through a relay. Nice Now just connect one pin output from the LPT data port to relay. It can be programatically controlled through a very very very simple program in .Net. you need to download inpout32.dll for xp, and inpout64.dll for vista/win7. You can search for "Parallel Port Programming" + C#.Net + inpout32.dll. You have the program.
5) For controlling Fan, you can have a regulator with each step connected to a relay. Never try for a Heater and Refrigerator!!!!! You can even go for TV on off.
6) Taking the Command
Options: a) Through SMS, GSM
b) through Bluetooth
c) Through Internet
d) Through Voice
e) Laser Light
f) TV remote
g) Telephone
Clarify, what method you are interested on. I will provide the guidelines. Trust me. It is a fab project. I Value the effort more than than anything for evaluating a project. Remember building a Radio by yourself is a better project than purchasing an INR 20,000/- project with RFID, ARM micro controller and so on. This is a work that you can certainly work into.
