check out the Catalex YX-5300 module. you can play up to 255 files from up to 255 folders. you can play one file at low volume, the next file at mid volume, a third file at high volume.it does not have a play random file function, but you can implement random files and random folders in code
am wanting to try something like this. I want to replace the idiot lights on my trucks panel with audible warnings. Such as 'warning, low fuel' or 'warning low oil pressure'. Using this module sounds like I could address such mp3 files based on the sensor input from the obd2 port on my Toyota? is this possible?
