VIDEO: NeoPixels and DotStars

Given their resemblance, why choose DotStars over NeoPixels? Some microcontrollers can’t produce NeoPixels’ steady 800 KHz data stream, and others might lose track of time. A separate clock signal helps DotStars receive at several megahertz or as slow as your device needs.

The Adafruit shop is packed with all shapes and sizes of NeoPixels and DotStars!

While controlling DotStars with vintage Atari BASIC may be possible, though not really practical, the demonstration did provide a Muybridge-esque answer to something I’ve wondered: does each DotStar sequentially assume its new color as data is received, or does the whole strip “latch” all at once with the end-of-data bits? Never got around to doing a low-speed test until now. And the answer is: the pixels change sequentially, but when used at typical multi-megahertz data rates it looks instantaneous.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
