IR Universal Send/Receive

[circuit_city]

Hello all,

Before I begin, I should mention I have successfully completed a similar project many years ago, so I know it's possible, but it's been a while and I can't find the code I originally used for relaying IR codes (or any other suitable solution, I've searched all over the internet and tried many pre-written solutions before reaching out via forum)

The program objective:
-Capture ANY tv IR codes
-Replay the codes on demand

The Application:
-Regulate TV volume via electret microphone

Logic of the program:
-Set desired TV volume via button and microphone
-Set remote Vol_up and Vol_down codes (eventually will save codes in SD card)
-send Vol_up or Vol_down IR signal based on microphone input (volume range).

What I've been able to do so far:
-The microphone portion is easy, I can view analog values of the microphone and set the volume range parameters

What else I need to do:
-Capture 2 IR codes and save them to deploy when the volume is out of range

Libraries I've tried to use:
-IRremote.h (obsolete)
-IRLib2 (not universal, or maybe I just don't understand it)

Components used:
-Arduino UNO
-Electret Microphone
-38kHz IR Reciever
-2-pin Buttons
-5mm IR Transmitter
-2N2222 Transistor
-Resistors, LED's, buttons, etc

Seems simple enough, but I would like the device to work for any TV, not just my specific model. Any help with IR signals would be greatly appreciated.

Thank you all!!!!

I can't find the code I originally used

Why not do the same as You did the first time? Go the same way to find the solution?

[circuit_city]

I believe I was using the IRremote library, which no longer works (that library utilizes WProgram.h, even the example sketches don't compile)

[Railroader]

Okey. Focus on the functions You used in that library and search for them in a more modern library.

So you have code that worked with the ancient (pre Arduino.h) IRremote library? And you need to make that code work with the newest version (>3.0) version of the IRremote library?

[circuit_city]

I had no idea there's an updated version of IRremote. This solves my problem, thank you so much!

Be aware that the new version works quite a bit different from the old version. Read the documentation and example code to see the difference and how to fix older code to run under the new library version.
