How do I make an RF remote control? Answered

How do I use these? (http://www.vegakitindia.com/productdetails.asp?ProdID=RF01A315) I need a complete step by step guide on how to make an rf remote control... I'm used to AVRs. But remote control is new to me.?

Sorry if this has already been asked, i couldn't find anything to-the-point

Suggestion: Use modules for which you can find instructions/examples. If you can't find documentation, continue shopping.

+many. The number of these half-assed webshops who sell you a module with no data is too many to count.

What exactly do you want to do? This may not be the best or easiest way to go.

In general your going to need a micro controller to drive these modules to provide the intelligent signal.

Your plans may be limited by local radio restrictions or the usually low range/line of sight qualities these type of modules have.

More details required.

You'll need some smarts at the receiver end, like someway to address each module, some CRC code, preamble generator etc

yeah...... I dunno why im not getting any notifications from the instructables bot. Sorry for that...

Yup yup, I can use the atmega for the brains, (addressing, data, encoding, decoding, etc)..
But still I dunno where to start...

Well that other comment of yours is influencing me to go ahead and experiment.... :D

Well....... It would be so much helpful if someone would write an intro to rf remote control and show us how to send and receive signals...... make a switch, perhaps? Arrrghhhh,...!!

I dunno. If you can find a COMPLETE datasheet, buy them. Usually you can direct serial comms into the input of the transmitter and pick up the same bitstream at the output of the receiver....there are lots of tricks to learn too. Make sure the RF signal is transmitted in a Manchester encoding too.
