/*
 * 
 *  IxLab 2020S -  NYU Shanghai
 *  recorded during class 17 - Digital & Analog
 *  Ideas for exercises to practice: 
 *  try changing the logic: the button controls the time; the potentiometer controls if it works or not
 *  change the pin number of the components
 *  add a second LED
 *  
 *  Based on AnalogReadSerial - http://www.arduino.cc/en/Tutorial/AnalogReadSerial
 *  This example code is in the public domain.
