I am building a prototype for an idea involving a zoetrope type mechanism ( http://www.youtube.com/watch?v=3-rPn0a56WE ), but I have practically no electronics/programming experience. I only need one small electronics component for the whole thing to work; a magnetic sensor run through the arduino to the iphone to trigger its LED flash. The rotating zoetrope disk will have small magnets along the edge to trigger the sensor, which causes the LED to flash in sync with the rotation speed. I also to be able to use other iphone apps simultaneously as the LED is flashing, such as the video camera.
Again, i have zero electronics experience, but i feel this is a fairly simple task.
Any advice appreciated! Thanks, Slam
