LED Clock Final Build 

Building an Arduino controlled LED clock. I designed a clock dial to hold 0.12in diameter PMMA fiber optic tube that illuminates (side light). This build utilizes a 60LED per meter WS2812B led strip and a DS3231 clock module. I don't go through the Arduino setup.
The build is not fully complete as the power supply and the acrylic LED holder has not been wired into the Arduino yet and the wooden housing for the Arduino has not been stained/finished and fastened down.
Code for the LED sketch along with 3 buttons for resetting time from the clock by itself. Also, I'm new to Arduino coding so I won't be very helpful for questions on the following code. I added web references for where I collected various code segments.
