Christmas tree-shaped infrared voice assistant

(It seems that the project cannot be renamed. The original project was called "Christmas tree-shaped infrared voice assistant" but after saving in the editor, it became "Christmas tree-shaped infrared voice assistant", so I made a copy and changed the title a little shorter. Now it shows that the project was copied, which is quite unpleasant.)

The base plate can be used directly after the components are welded on it. The Christmas tree vertical plate is used for aesthetics or flashy functions.

There is a MUSIC_PAD that is used to input and control the flashing effect of the LED lights on the edge of the Christmas tree. You can connect an external signal source yourself, or you can connect it to VCC through a resistor to keep it on. I have a music integrated film (the music of "Für Elise"), and I use it to extract the signal and connect it.

For the Christmas tree vertical board, you need to remove the five-pointed star from one piece and cut it in half for welding. This way you can make full use of the free sampling opportunity. Otherwise, you will have to proof twice to make two types of boards.

The flying wires in the video and cover image have been corrected in the new project, but there is no proofing verification, so if there are any problems, please feel free to make corrections. Thank you very much.
