Arduino code to send a synchronizing signal to cameras
// JB 20130421
// output square wave + LED frame counter + LED sub-frame measurement
// Square Wave: sent to FSIN on the cameras, maintaining the frame rate
// Counter: LEDs count in binary for each frame
// Sub-frame: each of 8 LEDs lights up in turn, 1/8th of the way through a frame
// constants for pins
// pins for input switches
