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 (you cannot set the LED to be individually dimmed, as in 'grayscale'). There's a few extras as well, such as being able to change the...

Ever looked at a wall in your apartment and thought "hey this could really use some art, or maybe an eye-blistering LED wall"? We do every single day! Then we finally did something about it, building our own full LED video wall using the 16x32 LED matrix panels in the shop. The magic sauce required is this driver set, which converts standard DVI video to an Ethernet datastream. The transmitter can decode/drive up to 1280*1024 pixels....

This is the magic sauce in our 7-segment and matrix backpacks, now available in breadboard-friendly breakout board format. The HT16K33 is a neat little chip that has the ability to drive a multiplexed 16x8 matrix (that's 128 individual LEDs). The communication protocol is I2C so it uses only 2 pins, and you can have up to 8 selectable I2C addresses so thats a total of 8 matrices, each one controlling 16x8 LEDs for 1024 total LEDs. Unlike our LED...

When you need some help driving a lot of LEDs, the MAX7219 is the best friend you could hope for. Many of us know that if you want to control a lot of LEDs, you'll want to use multiplexing, a technique that lets you control 64 LEDs (say) with only 16 pins (8x8). The annoying thing about 'plexing is that you need to use 8 power transistors (or a power register/latch, that can supply over 100mA per pin) AND you have to constantly refresh...

As an added bonus, the 180+ works of original pixel art commissioned for the Kickstarter project comes included too.   PIXEL has two...

Octolively modules are tileable, digital interactive LED surfaces filled with ultrabright LEDs that respond in complex and gentle ways to stimulus provided by human interaction. Each Octolively module is 4 X 8 inches (10.16 X 20.32 cm) in size, and features eight huge (10 mm) ultrabright LEDs, spaced along a two-inch grid. Each Octolively module also has eight infrared proximity sensors-- one for every LED --to detect nearby motion, even in...

Blinky Grid is a 7x8 LED grid kit from Wayne&Layne that has an ingenious method of programming. Instead of connecting it directly to your computer using old fashioned 'wires' - the board is held up directly to your computer screen, and an easy-to-use web page will 'blink' in the text or image you want. Its a fun and simple kit but with the bonus that you get to make it look the way you want when done, without a...
