/* This sketch is heavily based on a demo code by 
[Angelo qiao](Angelo.qiao@dfrobot.com) for DFRobot,
but it replaces the function that plays a new mp3 file after 
a set period of time with a function that plays a new mp3
file when triggered by an external sensor, either a PIR, 
doppler radar, or even a button*/

This sketch allows an Arduino to act as a speedometer. Data input can come from
magnets glued to the rim or spoke of a wheel along with a hall-effect sensor or
reed switch. You can also use an optical sensor using the spokes to break the
beam of light.

(If you use a reed switch instead of a hall-effect sensor, you will probably
need to modify the sketch to include some debouncing. If you use an optical
sensor, you might need Schmitt trigger circuitry.)
