/*  Color Clock
    E-Fabrik' 2018 - Pop [lab]
 
    A clock-like object changes color according to which part of the day it is.
 
    ########
    WIRING :
    ########
    Plug a DS3231 chip on 5V/GND
    SDA > A4
    SCL > A5
 
    Use DS3231 lib examples to set the time.
    Warning : Time must be set using summer-time (no daylight saving) for this code to work properly.
 
    Ledstrips on 5V/GND
    DI > pin 8
 
    Simple switch on 5V/GND
    reading > pin 2
    --> HIGH : Summer time, no daylight saving
    --> LOW : Winter time, daylight saving (-1h)
