Need Simple Modification to Infra Red Circuit and HEX FIle

[NishantSood]

Hello Friends,
I have a circuit of a Infra Red Receiver controlling 1 relay at a time but i want a circuit that will control about 4 relays at a time which can be started/stopped with linked 4 buttons on a Infra Red Remote.

The Circuit and Software(HEX file in text format) for the PIC 16F84 is GIVEN BELOW:

Please tell us about your compiler, attach the souce code.

is your program able to decode the remote codes ( codes like RC5, sony, NEC...)

I can't say your code supports any remote code decoding by just looking the Hex file.

your second thred Making IR Receiver using PIC16F84, ability to control 4 Different relays https://www.edaboard.com/threads/193286/#post810854 will surely work and decode RC5.

use any 90 channel remote.

What can be Done About Interference with other IR Devices? ,Like Signals from other IR Remotes, I mean RC-5 will definitely save my device from interference with other company remotes than PHILIPS but what about if i have PHilips TV or other appliances ,will Interference Occur?-------My remote Circuit Works over 38Khz

old codes like RC5 are not used in latest TVs. now they switched to RC6.
if you have any old 90 channel tv. then you have a problem of interference.

But Even if there is a problem of interference with old 90 channel tv remote, is there a Remedy?, The much i know i'll be using a Shield or plastic transparent cover of relative thickness so that it becomes mandatory to point in the direction at which device reciever is located, what you think ,WIll it Work?

there is no remedy for interferences.
Normal IR remotes will work + or - 30 degree angle only. if its a small area, refleted ir rays from walls also trigger an interference.

One Last Query what about TV's with 100 Channels ,Are 90 Channels TV's and 100 CHannel TV's same?
