to make a wireless remote for on/off switch

[Amit Agarwal]

how can i make two wireless remote for a car, which can lock or unlock the car door.

i mean to say that two or more transmitter (remote) for a single receiver.

please help me, if anyone have the answer for it………

make use of 2 or more switches with RF intrfaced with decode and encoder…

 

give switches output to Rf  Transmitter input  for encoder(HT12E) and then get the reciever output with decoder(HT12D) and control as per the switch

Hi,

      I want to make one wireless rover using HT12E/12D with RF module.

     

      But the problem is HT12E/12D had to process only four bit data, and

 

      it have able to control two motors at a time, behave  it is like a motor going FWD/REV only.

     

      so i want to control four motors at the same time. please refer any 8bit Enc/Dec ic for complete

     

      my project.

Plz …..
 

        I want to use HT12E & HT12D and RF module TX & RX , to transmitt 8 discrete digital data 4.3

 

         volts OR 0.5 volts ………..

         Can these data be the input for the ht12e directly ???

 

          HT12E has 4 input …… how can i transmit 8 input ???
      

          Can i use two one’s ???

Hello Anand,

 

                   Try to get datasheet of these…… HT640 and HT648L

It is a 8 bit encoder and decoder…………for RF

i want a circuit diagram for 

wireless remote for on or off application
