content: 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 remoteI 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.

content: The short answer is "yes". The long answer...have you actually tried googling "arduino IR remote control" ?http://www.righto.com/2009/08/multi-protocol-infrared-remote-library.html

content: You might also checkout the jp1 groupshttp://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).

content: 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.

content: 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.You may use also your PC, have a look to:http://winlirc.sourceforge.net/PeLuLe
