warning sounds

#1 Post by maak_pk »

hello
i am trying to play warning sounds and that too, on separate speaker/headphones where i dont get the sim sounds. is there a way that i can select the output sound card if i have two different sound cards or i can play the warnings on Arduino?
hope someone here has already cracked this issue
regards

No, it uses your primary sound device. If you would want to play a sound on an Arduino then you'll need an Arduino with a DAC or if it's a buzzer of some sort, buy the hardware version.

Another option is to bypass the standard sound system completely and add a Adafruit FX sound module connected to your Arduino, then trigger one of 11 sounds on that board. There are two versions, one which drives an amp, the other has an internal amp and you just connect speakers. IF you need more than 11 sounds, you can simply add multiple copies of the Adafruit board.

Thanks for this finding!
That Adafruit FX sound card seems to be quite a gem, 16Mb of memory, fully standalone, and a mere drag and drop of wav files from your PC.

Each sound can be triggered via a button hooked to one of the pins, so I guess that an Arduino and AM could be the man in the middle.
The basic effects on the sounds (loop, latch,sequence) are done by giving a specific name to the sounds. Simpler than that…

HI Jaques,
There is another nice option
https://www.aliexpress.com/item/4000158 ... 4c4dRlRgS4

Somewhere I have both the 8MB (64Mb version) and also the SD card version - which is up to 32GB - yikes. Both are crazy cheap. I did test them a year or so ago and they worked great. I used a serial connection. It gave full track (individual sound) selection and even digital volume control etc. Very neat.
Its another option and so crazy cheap.
It also does MP3 which is nice, but not absolutely necessary of course. Very nice, neat unit and full drag and drop from the PC as well.

Yeah, that’s even cheaper and the amp is 2x5W instead of 2x2W
The programming mode seems to be even more powerful.
I will order one just to play with, guess that it could be piloted via AM and an Arduino by emulating buttons.

Thanks

Hi Jacques,
Just a small note, the output is mono, not stereo, it will give 5W into a 4 Ohm load (around 3 into an 8 ohm load). so as most car speakers are 4 Ohm, they can be a great cheap option - or fed to a mixer on the pedestal.
Mono is, imho, a better choice for our kind of use. There is absolutely no reason not to have multiple units if needed for simultaneous and/or independent outputs all fully controlled.
The modes offered are FAR more comprehensive than the Ada unit. Yes, certainly 'normal' Arduino AM could be used with button etc, or indeed, messageport with serial (9600 Baud N81), or even one wire protocol. (I think it is the 'Dallas' 'one wire' protocol but would need to check that ?)
You could have a rack of them.. :D
Lovely units.
