I expanded the RGB LED matrix project from a single 32×32 panel to six panels to form a 24″ by 16″ matrix of 96 by 64 LEDs. That’s 6,144 RGB LEDs or 18,432 individual LED chips. The entire matrix has 12-bit color and a 200Hz refresh rate.
The video demonstrates seamlessly looping 3D Perlin noise, an audio spectrum analyzer, a generic falling blocks video game, still images, animated GIFs, and a short video clip all running on the BeagleBone Black and being displayed on the 96×64 RGB LED matrix.
After the demonstration, I turn the panel around and walk through some of the significant parts of the mechanical construction and electronics.
Complete details on the project including links to the source code and mechanical design can be found on this page of my blog….
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
