We’ve just thrown the switch on a new Arduino library for creating LED matrix displays using NeoPixel LED strips, pixels or shields. All the functions in Adafruit_GFX are then available: lines, filled shapes, text, etc. The photo above shows three separate 10×8 matrices made from NeoPixel strip (240 pixels total — 4 meters of strip), tiled together into a single display…the library takes care of all the permutations! It’s also a great companion for our NeoPixel Shield.
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.
