I tested three inexpensive, easy methods to add LED lighting to my modular 3D‑printed lantern using USB power: reused LED modules, short 5V strips, and WS2812B RGB with a microcontroller. I share parts lists, soldering tips, diffuser advice, and firmware steps—read on for step‑by‑step instructions and printable models.

I’ll walk you through creating custom patterns for your snowflake decoration, covering double-buffering, frame-sync, non-linear PWM, fixed-point math and the scene interface in C++. If you can solder and use an SWD programmer, read on for practical examples and a ready-to-edit User scene template.

I tested 13 SMD LEDs for my plant-watering sensor project, soldering them to a small board and driving them from an Arduino Zero Pro to compare brightness and flash styles. I share photos, part numbers and a short demo video — read on if you’d like the full results and notes.
