Circular light panel 2812

Overview

This is a modification based on link-who's Air001_ws2812B.
Many thanks to the many people at JLCPCB's open-source community; I, a complete beginner, have learned so much.
The original project had 18 5050 LEDs; mine has 60+24+12 LEDs, with a size of 2020.

Soldering the 2020 version was very difficult.
The original plan was to create a 3D-printed frame, a diffuser, and a semi-transparent brown disc.
The outer 60 LEDs would display the minute hand, and the middle LEDs would display the hour hand, with the outer ring also displaying the second hand, consuming minimal power.
However, after the Spring Festival, the 7 yuan shipping fee and price increase from Hezhou made this AIR001 solution seem unappealing.
Programming was also fraught with difficulties. Initially, I used Arduino programming with SPI.H, but it kept having bugs.
I modified the code from link-who, but only managed to display the minute hand with the outermost 60 LEDs, and then encountered more problems.

I can't solve it for now, so I'm just releasing a PCB as a milestone—a first-time release commemoration.
