Arduino-Yolka 2, Christmas tree. Programmable Constructor

The electronic designer consists of three boards - two boards are branches of the New Year Tree, on which there are 100! address LEDs SK6812mini and one board is the base of the Christmas tree on which the Arduino controller is assembled.
The boards are connected to each other in a festive tree. The kit includes a USB-UART converter, with which you can program various lighting effects on the branches.
In production, the Yolka was programmed with the "rainbow" effect.

We helped you a little - soldered the LEDs to the "branches" of the Christmas tree on one side and completely assembled the base.
Install and solder 9 terminal ceramic capacitors and one electrolytic capacitor. And on the branches you will need to solder the remaining fifty LEDs. Don't rush, without them, too, everything works and is very beautiful! You can add several LEDs per day.
