// A simple Teensy based USB keyboard that associats some kind of
// physical motion event to a 'w' press. This can be used to advance Google StreetView
// for an interactive exercise experience (Example here: https://www.instagram.com/p/CF-xVWgJiFK/)
//
// Must select the "SERIAL+KEYBOARD..." mode under "USB TYPE" for the Teensy!
// 
// This version uses a Sharp IR sensor (or equivalent), connected to A9 pin of a Teensy 3.2
