HOW-TO: Animating Multiple LED Backpacks @ The Adafruit Learning System. Lights! Action! MORE LIGHTS! MORE ACTION!

Adafruit LED backpacks make it incredibly simple to add small bitmapped displays to a project. Each requires just four wires: power, ground and two communication lines to a microcontroller.

Two common questions we receive:

  1. How can I use more than one 8×8 matrix backpack in an Arduino sketch?
  2. Can I have two (or more) matrices always showing the same image?

This tutorial demonstrates both.

We’ve had spooky Halloween displays on the brain lately, but the concepts here are equally applicable to more benign concepts!

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.

  1. Here is my version of this project, using the 0.8″ LED matrix/backpacks:

    I really enjoyed putting it together – thanks for the idea and tutorials (oh – and the source code!). The skull is a temporarily re-purposed candle holder. An Ardweeny powers the sketch (my Adafruit ARDX would not fit into the Brainial Cavity).
