NEC Infrared Remote

Gaurav Chaudhary  writes:

This little project will demonstrate how you can build NEC protocol based Infrared Remote Control to use with various NEC Protocol IR receivers.
actually there are lots of projects out there to accomplish this task but i have to write my own code because of too many requests on this IR(infrared) Remote Control Relay Board with PIC 12F675 Microcontroller people keep asking “Where is the Transmitter for this” although you can use any NEC protocol based remote ,but i just wanted to build one by my self. so here it is.

Visit Gaurav’s website for project details.

    Dear Gaurav.
    Thanks for the project & your response to many questions asked by people. I have gone through all those and very much appreciate your patience.
    I need your help, if you please.It is here…..
    I constructed one ir remote control for FAN on/off & its speed whose HEX file of the RECEIVER only was available in the net. This author suggested to use CAR MP3 player remote control as hand set. Entire unit is working fine. Receiver is with 12f675.
    Now I want to make the transmitter part.
    Kindly provide me the codes.
    Car MP3 handset has 21 keys & I do not want them all. Only ‘ + ‘ ‘ – ‘ ‘ 0 ‘ and ‘ 9 ‘ will serve my purpose. Kindly help me. please use 12f675 here
    Thanks & regards
