NeoPixels & Dotstar
The NeoPixels and DotStars are smart LEDs and the only one capable to produce an colorful explosion of light. Each pixel can be set individually. With NeoPixel, only one pin is required on the MicroControleur (Arduino, Trinket, Trinket Pro, Flora, MicroPython) to control all the LEDs et build a 24 bits color panel for every LED. The DotStars is an evolution of NeoPixel technology using a SPI bus based to controle the LEDs with hardware SPI or BitBang SPI (software emulated SPI). DotStar are really convenient to create Persistance of Vision (POV) animation.
