Build and customize your very own open-source button grid controller. This DIY kit comes with delicious translucent button pads, driver boards, diffused white LEDS and a custom laser cut enclosure. The result is a sturdy and elegant but also super-hackable controller device for music, video…or something else???
These LED panels take care of all the work of making a big matrix display. Each panel has six 8x8 red matrix modules, for a 16x24 matrix. The panel has a HT1632C chip on the back with does all the multiplexing work for you and has a 3-pin SPI-like serial interface to talk to it and set LEDs on or off. There are a few extras as well, such as being able to change the brightness of the entire display, or blink the entire display at 1 Hz.
Bring a little bit of Times Square into your home with our 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. Learn how to get these LED matrices up and running with an Arduino.
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.
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.
