I have to design an interactive installation for a museum, which has to play 2min audio files on specific trigger event.
The device must be powered for a whole year.
And i really need to make sure the device will perform ok for that time
If someone have experience with such a longtime projects, please let me know.
Any other suggestions about platform or reliable audio board will be appreciated.
I am concern about the shield and the sd card. (reading errors... or stuck playback or something)
