The NeoPixel ring is just for show as the actual time is displayed on the four 7-segment displays. In the video below you can see it changes animation sequences at the top of every minute – and boy is it bright when it’s bright! Full bill of materials, schematics and code are here at Hackster.io.
The project has 6 different algorithms to animate the clock. They switched randomly depends of the current time. The ring led color changes randomly too.

NeoPixel Ring – 24 x 5050 RGB LED with Integrated Drivers: Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6″ (66mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock. Read more.
