/*
 Grove Light Sensor

 A simple program that display the value of light from the Grove Light Sensor
 on the Grove 4-Digit Display, this example is very similar to the Grove Rotary Angle Sensor example
 
 The circuit:
 * 4-Digit Display attached to Pin 38 and 39 (J14 plug on Grove Base BoosterPack)
 * Light Sensor attached to Pin 24 (J6 plug on Grove Base BoosterPack)
 
 * Note:
