I have to design an interactive installation for a museum, which has to play 2min audio files on specific trigger event.
Sounds like a nice project. perfectly doable.
What sort trigger do you have in mind?
The device must be powered for a whole year.
use a decent power supply.
And i really need to make sure the device will perform ok for that time
We can review code and schematics from here.
be sure to put all things in a nice box.
If someone have experience with such a longtime projects, please let me know.
The Arduino will not be the problem.
Any other suggestions about platform or reliable audio board will be appreciated.
this seems to be a good start for you... - Audio Shield for Arduino -
