What are you trying to do, i want to see if we can help make a better solution then a bunch of media players
Ok, fair enough. I am planning a bunch of units that each have a set of simple sensors inside, light, PIR, etc with a corresponding arduino. When the PIR is tripped, based upon the input from the other sensors, I want the arduino to trigger playback of one of a set of six to eight 20-30 sec sound recordings. (it is essential for the idea that it be sound recordings, not bit-banging pitches, or other "synthetic" sound)
I thought that the best way to do this would be to control a media player via RS232 or other serial control protocol... But I am totally open to suggestions. I don't have tons of experience doing low-level prototyping, but I am willing to learn if there is some resource to work from.
Thanks again for all the help!
