UPDATED LIBRARY: the latest release (1.1.0) of the Adafruit_Protomatter library for various 32-bit microcontrollers adds support for “tiling” multiple RGB LED matrices into a single large canvas for graphics.
RGB matrix tiling is already present in CircuitPython 6.2-beta. Now it’s available on the Arduino side as well — anything using the Adafruit_GFX drawing library can span multiple matrices. Basic use is documented in the library’s “tiled.ino” example sketch, while matrix topology and power are best explained in this CircuitPython guide (the concepts are equally applicable to Arduino).
Adafruit_Protomatter and Adafruit_GFX can be installed or updated in the Arduino Library Manager.
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.
