I am working on Home Automation Project using "RF" Technology. In that I have to operate more than one switch board or let say more than one "Relay Board" using single "RF Remote". So I want to know, is it possible? And if yes, How to do it using "RF and Arduino"?
Are you planning to use an existing RF remote (in which case post a link to its datasheet) or are you planning to make your own using, for example, nRF24L01+ transceivers?
Also you need to tell us in more detail what you want to control and where they will be located relative to the receiving Arduino.
I am going to use existing RF Remote...Right now I have just started to working on it...so I don't have specific datasheet.
And for location or thing to control, Location will be as our Switch Boards are located in our house and I have to control Home Appliances.

I presume that means everything will be close to the Arduino - say not more than 2 metres away?

Yes arduino will be there on every board....

That sounds like you are planning to have more than one Arduino.
Handing out information drip-by-drip and requiring follow-up questions just wastes everyone's time
Give us a comprehensive description of your project.

Sorry for this.
Yes I have more than one Arduino.
For comprehensive descriptionof project I would say, I have single RF Remote and have to operate more than one Relay Board with more than one Arduino i.e. each Arduino will work as Reciver and will operate relay board connected with respecting Arduino. So How can I do this?
That's not my idea of comprehensive. And I am getting very tired prompting for more information - i.e. this is the last time.
You have not even told us what sort of remote control transmitter and receiver you have.
And if you don't have datasheets for them I suspect this project is a non-starter. RF projects can be difficult even when you have all the data.

Hi,
Can you tell us or post a link to the RF remote you are going to use please?
What are you going to use for receivers?
A single arduino controller can operate more than one relay.
Can you post/attach a simple block diagram (CAD or picture of hand drawn) of how you would like to have your home system setup?
Can you tell us your electronics, programming, arduino, hardware experience?
Thanks.. Tom.. 
Look at some of things here

Like this one
Give the receiver power & Gnd, it has 4 outputs that go high corresponding to a button push. Very easy to read with Arduino and take some action.
You could unsolder the similar board off one of the 8 & 12 channel units & do the same. They've declined to sell just the remote & receiver to me in the past, too low a quantity requested I guess.
