Day/Night Clock

*Update 7/6/17:* Added sketch used to display the clock.

This is a clock I built for one of my sons who was having trouble knowing whether it was day time or night time

This design allowed him to know whether it was day or night and to get a visual sense for how much time was left before either.

Parts:
--------

* Neopixel ring for Particle Photon / Core
* A Particle Photon or Core
* A print of the neopixel_ring.stl to house the neopixel ring itself. I used some double sided foam tape to ensure it doesn't fall out.
* A print of the front of the case (the ring print should press fit into it)
* A print of the back of the case (the front of the case should press fit into the back)
