RGB Christmas tree

 
Overview
       Jialichuang is open source. The schematics and PCB are both open source. I moved them here and modified them a little. I made the program with a friend. I used WS2812B lamp beads for RGB. The cheapest ones are 0.15 each on Taobao. It takes 0.15 to make a finished Christmas tree. 136 RGB lamp beads, the total cost of all components will not exceed 50.
