“Dotstar LEDs are super fast and super bright — they’re the best LEDs available for drawing persistence of vision images or light painting. This guide combines Dotstars with a Teensy 3.2 — a super fast Arduino-like board with 256K Flash Memory and 64K RAM. The Teensy has enough space for hundreds of images and patterns, so with a little time and a little imaging knowhow, these poi can go all night without ever repeating a pattern.”
