Hello,
I'm an artist in Miami Florida, i'm working on a piece (on a shoestring budget) which would allow an analog music box ( This item is unavailable - Etsy ) to be sensed by the arduino through a mic(?) which would then simultaneously broadcast the sound (wirelessly?) through speakers and create movement in 5 dc motors which would allow five metal sculptures (weighing a little more than 10 pounds each) to spin (on bearings or pulleys) at different rates of speed (speeding up and slowing down at low rpm) and change direction, hopefully independently? i saw an extender shield ( http://www.liquidware.com/shop/show/DTX/DoubleTall+ExtenderShield ) and figured maybe someone knew whether it would fit my needs for controlling multiple motors or if multiple H-bridges would be better? I'm a total novice but i do have the assistance of an electrical engineer but he is also an Arduino novice...
Thanks Again And Best Regards,
Casey
