    hello..

    I am new to RF could u please help me 

    to interface RF transceiver with ATmega16 using HT12E and HT12D..

    and controlling a relay on receiver side..

    Also I’m trying to interface 4×4 Keypad and transmitting 10 digit number to receiver..

     

    Thank you.

    hi

    you are saying that to transmit 10 digit num

    is it binary or decimal ?

     

    actually

    HT12E is a 4bit binary encoder

    HT12D is a 4bit binary decoder

     

    there are 8bit and 12 bit encoder and decoder are avilable

    try “google”

    you will get it

     

    if you got 8bit encoder please send me the details of the shop

    You can communicate in one direction if you use HT12E & HT12D as the RF modules used are RF Transmitter and RF receiver so for two way communication you will require an HT12E & HT12D on both sides one side transmitting on 433Mhz and the other side transmitting on 315Mhz.

     

    Or you can use RF Transreceiver module: http://www.dnatechindia.com/WIRELESS/CC2500-RF-Transreceiver-Module.html

    hello

     you can sent unlimted data using microcontroller on transmiiter side like(atmega8).

    supoose you want to send 8 bit data you can broken it into two nibble and transmit .

    so you have to make your own rules to transmit data.which will apply on both side microcontroller.
