/*  Light Curves for Exoplanet search demo sketch 
 * 
 * This sketch calculates the brightness vs time coming 
 * from a light bulb representing a star and a spherical object 
 * representing a planet orbiting around the bulb.
 * When the planet is transiting directly in front of the star 
 * there are dips in brightness.(The light sensor is 
 * in the plane of the planet). 
 * 
 * This draft sketch was written during The Physics with Arduino School  Arduino Physics School 
 * organized by Sapienza University, Rome (Prof. G. Organtini).
 * 
 * Components
 * ----------
 *  - Arduino Uno
 *  - light sensor
