“I’ll be describing how we made this analog clock that double functions as an advent calendar. There are 24 ws2811 leds around the clock in a circle and each of them light up green to the days before Christmas. On Christmas day, all the lights are lit red. During every other month the lights are a solid blue color. It’s driven by an es8266 that can be managed by the Arduino IDE, but a raspberry pi would also work. This can be highly customized and changed to your liking, and it can even run animations outside of the normal solid colors. Keep reading to learn how I made this, or watch the video below!
