Binary clock using Arduino, DS3231 real time clock, and WS2811 Addressable LEDs

You may have remembered I started working on a binary clock project with the Arduino. There are two things I didn’t like about that project. First, the clock didn’t keep time. It ran about 37 seconds fast. Second, it required the use of almost all pins on the Arduino. I started working on a new binary clock project with the requirements that it kept accurate time, it didn’t use as many pins, and I could set the time. I sacrificed the addressable LEDs I had used for my Christmas Tree Lights and began to work on the new binary clock.
