/* 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*/
