By using these driver ICs, the complexity of wiring and control is significantly reduced. “I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano.

The clock part works as you probably expect — an Elegoo Nano fetches the time from a real-time clock module and displays it on the WS2812B LED strips arranged in 7-segment formations.
