Use spare TV remote buttons to replace Amplifier remote

Projects General Guidance
1

Hi,

Here's my project:

I've got a remote for my TV and a remote for my amplifier. The TV remote has spare buttons and the amplifier remote only uses 3 of its 30 buttons, vol+ vol- and standby.
What I would like to do is to use the spare TV remote buttons to do the tasks that the Amp remote does.

Start off by reading the respective IR codes for the the two remotes, this I have done before for another project ie 0x100BCBD

Then....

If I had an Arduino connected to an IR receiver and also an IR transmitter, would it be possible to read the IR code when a TV remote button is pressed and convert this to one of the amplifier codes, then transmit this code via the IR transmitter to the receiver in the amplifier?

Someone must have done this before but I can't find it...

Can anyone point me in the direction of where I can find help on this project.

Many thanks

Ron

I have, getting the Volume control may be an issue. In my setup, when I press the power for the TV, it also turned on the amplifier. The issue with the volume is repeating the signal, as you would be sending 2 signals at the same time..

That's sounds the sort of thing .... so, there are like minded folk out there!!

I'm intrigued, please tell us more about what you did.

Thanks

I decoded the amp remote, then wrote code to read the IR, when it saw the code for 'Standby' from the TV remote, I sent the decoded amp remote code.

Have a look at this as he is doing exacly what your proposing.

Hi,

Thanks. That's the sort of thing I was looking for.
