32x16 and 32x32 RGB LED Matrix
512 pixels of eye-blasting glory
Bring a little bit of Times Square into your home with our 16 x 32 and 32 x 32 RGB LED matrix panels. These panels are normally used to make video walls – here in New York we see them on the sides of buses and on bus stops – to display animations or short video clips. We thought they looked really cool so we picked up a few boxes from the factory. One has 512 bright RGB LEDs arranged in a 16x32 grid on the front, the other has 1024 LEDs in a 32x32 grid. Learn how to get this LED matrix up and running with an Arduino.
Tiny Arduino Music Visualizer
Maximum blinkenlights, minimum effort!
This easy project combines an Arduino with our microphone amplifier and bicolor LED matrix to create a music visualizer that responds to ambient sound.
Animating Multiple LED Backpacks
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. Here’s how to use more than one 8x8 matrix backpack in an Arduino sketch.
Adafruit LED Backpacks
Control small LED matrices with ease
What's better than a single LED? Lots of LEDs! The matrices use a driver chip that does all the heavy lifting for you: They have a built in clock so they multiplex the display. They use constant-current drivers for ultra-bright, consistent color, 1/16 step display dimming, all via a simple I2C interface. Here is a detailed guide showing you how to solder, wire and control the display.
FPGA RGB Matrix
Control large RGB LED matrices using an FPGA
Adafruit currently sells a really cool 16x32 RGB LED matrix panel in their store that is "designed to be driven by an FPGA or other high speed processor." The purpose of this tutorial is to help you get started driving a small handful of these displays with the DE0-Nano board, which contains a mid-range Altera FPGA.
FLORA TV-B-Gone
A tiny television neutralizer
The most wearable TV-B-Gone yet! Use freehand wiring with solder to whip up this pin capable of shutting off most television sets. Craft your own fabric ornament to match any outfit.
USB NeXT Keyboard with an Arduino Micro
Get out your 10 lb keyboards!
Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! We spent a few days and with a little research we got it working perfectly using an Arduino Micro as the go between. Now this lovely black deck works like any other USB keyboard. Sure it weighs more than our Macbook, but its worth it!
