I have some experience with coding and electronics, and now I am planning to start adventure myself in an Arduino project(god help me).
I have an old Samsung home theater with working wire speakers and a subwoofer, which I plan to use in a DIY audio controller project. However, before I begin, I have a few questions.
I am wondering what the best audio input would be for this project. I want to keep it as simple as possible, so I was thinking of using the auxiliary output from my smart TV and connecting it to the auxiliary input on the DIY controller. Would this be sufficient to process the speakers and subwoofer, or is there a better input I should use?
I have done some quick research and found that most people use the PT2322 or PT2323 Digital Audio Control Circuit. Is this the right path for my project?
I am wondering if there are any retail stores that sell circuit boards ready to use for this kind of project.
What DIY controller project? What are you hoping to achieve?
What DIY controller? If it has aux input, does it have other inputs? Are we talking RCA in, 3.5mm stereo minijack in, what?
This sounds like a pretty ambitious project but again, I'm not sure what you hope to achieve that isn't already handled by a bitstream/PCM signal from your TV to the surround sound DAC in your home theater set.
Is this the project you are following? https://320volt.com/en/pt2322-pt2323-arduino-5-1-digital-audio-control-circuit/
What is your specific parts list, what Arduino were you thinking of using and do you have any code (using code tags)?
I don't know if there are commercially available solutions to achieve your goal, since I don't know your goal.
Hi .
DIY controller is what I'm trying to build.
What i am trying to achieve is retrieve the audio from the TV (either via 3.5mm stereo minijack or RCA or Bluetooth,) into the controller and output the audio to 4 speakers and a subwoofer
and A nice to have would a remote controller just to adjust the volume. That's it.
And yes, the PT2322 PT2323 Arduino 5.1 Digital Audio Control Circuit is what I saw under my research.
On the page he has plenty circuit board going on, and that's what I try to understand where can I buy it.
Just to make more clear, a surround sound DAC is exactly what im trying to achieve here, once that my old Samsung home theater device isn't working well... Only the speakers are good
Your TV has an option to broadcast its audio stream over Bluetooth? Is the subwoofer powered or passive? What are the speaker impedances? 8 ohm, 6, 4?
I assume the amplifier in the surround set isn't working either? Is that correct?
I'll be honest because it saves time, yours and mine.
I don't understand where the Arduino comes into this. Audio signal processing, as you've alluded to with external ICs, is better managed by chips other than what's in the reach of amateur Arduino enthusiasts (including me).
If it was a project like using an Arduino to replace a lost remote, you'd be a little more dialed in to something that will satisfy your expectations.
So here's a question I think is relevant: are you building this for the experience of building in and of itself, as in the process of and (hopefully) satisfaction of an electronics build? Or are you hoping to really just enjoy the result, ie a home theater system that repurposes your existing speakers and subwoofer?
Please don't take this as harsh or me being a smart ass or anything, it just seems like a very ambitious project if you're really just after the end result and not so much the build process as a hobby unto itself.
Doing it just for fun!
And the Samsung hometheater itself is 100% (expletive deleted).
And not don't worry.. not offended at all, quite the opposite I appreciate your time and knowledge invested in help those crazy ideas of the community lol !
The thing is, I want start a project that have a minimum of propose, and when I saw my speakers and a subwoofer lie around my garage.. I thought "why not?" lol
That's pretty much it.. I want to use the subwoofer and speakers to reproduce my TV audio.. I thought on the Arduino because as far as I understand I need something to process the audio inputted and split between the speakers and subwoofer
Is that correct?
I just deleted my post since someone more knowledgeable than me chimed in, basically I said, if I'm correct, an Arduino can't do Dolby DSP through its ADC.
The only audio stuff I've done with Arduino is like, the tone library stuff, DTMF tones on an LM386 amp (which is great for basic greeting cards) and using WAV shields where a signal trigger activates some audio track on an SD card, amplification done off board to an external, commercially bought amplifier solution such as the Fosi Audio Class D family or even an HT receiver ( 1970s Marantz for 'uge Hallowe'en audio)
How close could one of the other boards come, out of curiosity? Such as the Arduino Due?
Is the type of DSP involved even in the same ballpark?
Sorry I can't help you get on track with your initial project, but if it helps, have you attempted repair on the pooched Samsung receiver?
Is it like, totally unworking? I ask because after unplugging and leaving for a day or so (caps can hold a heck of a wallop if you're not careful), I have been able in the past to easily repair some receivers by just taking the cover off and having a look. There's usually one or more small glass fuses near the power supply on the board ( usually where the power cord goes through the case) and if you're lucky, a repair can be as simple as replacing that fuse with the exact same one, it should say right on the fuse 2.5A or something similar and will most likely have a straight wire through it (solid state typical) and therefore is of the fast blow type. If it happens to have a wire that looks like a spring (likely not) then it's slow blow type.
What's the worst that can happen? It doesn't work anyway, right?
