Small Smily Lamp

It's a small lamp that can be powerd over USB. The lamp is smily-shaped and has a height of around 13 cm. The head is printed with natural colored PLA-filament, the Body, foot, mouth and eyes are printed with black colored PLA-filament. There are four buttons at the body to control speed, mode, color and brightness of the LED-stripe inside of the head. Inside of the body is a arduino Nano, which controls the WS2812 LED-stripe. The stripe I used has 16 LED at the needed length.
The Program is written in the Arduino IDE and comes with the STL-files. The body is a bit small so that the Arduino only fits when you did not solder the pins for breadboard and solder the buttons, LED-Stripe and Power-Cord (USB) directliy to the Arduino.

That is the LED-stripe I used: https://www.amazon.de/gp/product/B07TJCQ169/ref=ppx_yo_dt_b_asin_title_o03_s01?ie=UTF8&psc=1
