Small Christmas tree with multiple light effects.

List of additional parts:

-LED Ring WS2812-8-Generic Microcontroller Nano 3.0 Atmega328 USB-C-3x70mm cable pieces

Assembly Instructions:1.Solder a 70mm wire to the “DI” pin of the WS2812-8 ring.2.Solder a 70mm wire to the “5V” pin of the WS2812-8 ring.3.Solder a 70mm wire to the “GND” pin of the WS2812-8 ring.4.Insert the ring into the trunk.5.Pass the wires through the slot.6.Solder the wire coming from the “DI” pin to pin 6 of the Atmega328 Nano 3.0 microcontroller.7.Solder the wire coming from pin “5V” to pin 5V of the Atmega328 Nano 3.0 microcontroller. 8.Solder the wire coming from pin “GND” to pin GND of the Atmega328 Nano 3.0 microcontroller.9.Insert the Atmega328 Nano 3.0 microcontroller into the base.10.Join the base and the trunk by exerting pressure.11.Place the top of the tree on the trunk.12.Finally, insert the two parts of the star to fix the whole. Make sure that the WS2812-8 ring is properly fitted into the tree top.13.To prevent the integrated LEDs in the microcontroller from producing unwanted light, I recommend sticking a piece of black insulating tape on top of the LEDs.
