Remote IR Frequencies

[Raellz]

Since the remote control to my stereo was damaged beyond repair I've been unable to adjust the equalizer. Combine with my desire of electronics I was wondering if I could custom make my own IR remote using an Arduino Nano or something like that.

Does anyone know if this is at all possible? I understand how the signals work and that I would have to find the exact right one, but even if I cannot use it on my stereo I would be happy to have my own somewhat universal remote 

I cannot find much at all of this online and I'm a newbie so if anyone has any ideas or links to a good layman explanation on how to customize IR frequencies that'd be great. Thanks.

The short answer is "yes". The long answer...

have you actually tried googling "arduino IR remote control" ?

If you have a smart phone, you can probably get an app.

Not quite layman, but I'll read it over a few more times to see if I can understand. Thanks.

I just tried a couple. They... seem like a gimmick.  I guess they only work on TVs, not really "universal" I guess.

If you can borrow a remote from same make stereo, you can do the following

Thanks much.

You might also checkout the jp1 groups http://www.hifi-remote.com/jp1/, who have done a lot of  reverse engineering and have a huge database of information about the protocols and codes used by different gear. (As well as the programming for the "all-for-one" line of universal remotes).

What is the model number of the defective IR remote?  You can probably pick one up on ebay for $10 to $20.

Also, what is the model number of your stereo/equalizer?  Someone may have the remote for it and be able to tell you what the codes are.

Actually, that's about as "layman" as it gets and still fits your original question:

...custom make my own IR remote using an Arduino Nano or something like that.

(It's basic enough for me to understand it, which means it's pretty darn basic after all... but I do have some experience with Arduinos.)

You do not have to stick to an Arduino, but for sure you need to know a bit of programming it.
Any CPU, fast enough to generate the codes at the required frequency, is sufficiant.
I did an "intelligent" remote control in the late 90s on a 4-bit CPU (it's no typing error) clocked at 4 MHz, NOP instruction execution time 2us.
