Christmas tree sound ambiance lights

Christmas Tree Voice Atmosphere Light

Semi-mortal State

The running water lamp circuit does not light up. I don’t know what the problem is. I copied the official heart-shaped lamp circuit: https://oshwhub.com/course-examples/jian-yi-xin-xing-liu-shui-deng

There is also a problem with the dual power supply circuit, it can only be used by plugging in.

There are only two standard passwords, turn on the switch (turn on the light) and turn on the light (turn on the watercolor lamp), you can see the PDF of HLK-V20.
