Candlelight Emulation – Complexity with Layering

Posted on 2023-02-01— Projects

I explain microcontroller firmware that emulates candlelight using layered, low-resource random waves and simple integer math. I cover color gradients, LED mapping (WS2812B), and flicker modulation so constrained boards can produce organic light. If this interests you, please read the full post for code and details.
