New Project! Mini Commodore PET with LED Matrix #3DPrinting

In this tutorial, you’ll learn how to build and assemble a mini replica of the PET commodore. This isn’t necessarily useful or an actual computer, it’s just a cool prop. You will however, hopefully gain some experience, learn something new and have fun 🙂 There’s 144 LEDs in the Adafruit 16×9 charlieplexed matrix. It’s a classic LED matrix look that uses the IS31FL3731 chipset and can PWM each individual LED in a 16×9 grid so you can have beautiful LED lighting effects.

Tutoral on the Adafruit Learning System.

For a full list of parts, circuit diagram, code and files, check out the tutorial on the Adafruit Learning System.

Code written by Phillip Burgess @PaintYourDragon

// Animated Commodore PET plaything. Uses the following parts:
// – Feather M0 microcontroller (adafruit.com/products/2772)
// – 9×16 CharliePlex matrix (2972 is green, other colors avail.)
// – Optional LiPoly battery (1578) and power switch (805)

Taking a cue from our animated flame pendant project, this code addresses the CharliePlex driver chip directly to achieve smooth full-screen animation. If you’re new to graphics programming, download the Adafruit_IS31FL3731 and Adafruit_GFX libraries, with examples for drawing pixels, lines, etc.

Animation cycles between different effects: typing code, Conway’s Game of Life, The Matrix effect, and a blank screen w/blinking cursor (shown for a few seconds before each of the other effects; to imply “loading”).


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.
