TL;DR
John Park's article dives into a clever technique for wrapping NeoPixels—those vibrant addressable RGB LEDs—around a circular arrangement using CircuitPython. By applying the modulo (%) operator, he demonstrates how to elegantly map pixel indices to their positions on the ring. This approach simplifies the process of controlling LED layouts without the need for complex calculations.
