After completing my first BeagleBone Black + FPGA project and tutorial where I drove a single 32×32 RGB LED matrix, I decided it was time to go bigger. The result is this project —- a 3 x 2 matrix of 32×32 RGB LED panels. That’s 6,144 RGB LEDs or 18,432 LED chips—each of which can be controlled with 12-bit color at a refresh rate of 200Hz. Let’s take a closer look at the steps required to move from driving one panel to driving six panels.
Above is a video on YouTube of the six panel project in action.
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.
