WS2812 snowflake lamp based on ESP8266

Overview

This design uses ESP8266 as the controller and adopts a pluggable design. The ESP8266 minimum system board above can be unplugged and used alone. The supporting ESP8266 minimum system board project link: https://lceda.cn/wywy/esp8266-zui-xiao-ji-tong-ban has a battery and can be independently powered, getting rid of the constraints of the USB cable, and also adds a charging circuit, which can Charge the battery. Since this is the first version, some designs are not very reasonable in order to pursue smaller component footprints, and there is room for improvement. In the future, some networking functions will be added. The blink app can be used to operate the snowflake lamp. The design of the charging circuit will be more scientific to avoid the problem that the USB interface cannot be plugged in and out. After testing, it was found that IO16 cannot light up ws2812. Consider using only one IO port to drive all lights.
