IR Receiver For Any Remote Handset


 If you have a IR transmitter remote for any company, then you can design receiver for that particular company .There are some steps to make a  RF receiver


1-   Find the IR transmition code of that particular company  (Philips,Sony ...RC5 coding  etc..)
       Follow some steps.
         
       1.a--Copy the hex code that given bellow,  paste into new notepad and save as "irpic.hex"
          (you can give any name but extension must be   .hex  instead of .txt)

       1.b--Burn (program) this HEX file (irpic.hex) into PIC12f675 or PIC12f629 by using
               JDM Multipic programmer Click here
       1.c--Connect the circuit diagram as per the picture


       1.d--Download "IR Scope " Software ,for Download Click here
       1.e--connect  the serial port into your PC and Run  "IRscope"


              Set correct COM port and capture duration (700ms) and click on "capture" Button ,
              So you can hear beep sound then press any key from your remote control, After 700ms you      
              can see digital code (with timing) for  corresponding key.


                                                        Example for RC5 coding.


2--Make receiver circuit for corresponding detected code
         To design a IR receiver for particular IR code(that can be find from above method) please follow simple IR transmitter and receiver for my own code, after follow that project, you can make receiver for any IR code.To find that receiver design please click here 

(Don't  forget write the comments about this project)
