Hi, All -
I'm looking to trigger sounds on an old Android phone using an Arduino, but haven't been able to find much info online.
The project I'd use this for is a standalone audio sampler—I'd like to trigger drum sounds on the phone using an old Nintendo power pad connected to the Arduino. I thought about using a Sparkfun Mp3 shield or a single Waveshield to do this, but each of those can only trigger one audio file at a time, which will cut off sounds with a long decay (like cymbals) when the next sample is triggered. I guess I could technically stack a couple waveshields to have two samples play at once, but the logic there would be tricky, so I'd like to find a more elegant solution.
Does anyone know of a way to send commands via USB to an Android phone, or (even better) a method for triggering multiple sounds at once using an existing Arduino shield?
