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...

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...

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...

Beam is a beginner-friendly PCB with 120 LEDs arranged in a 5x24 grid, a great size to display text or animations in your project. Plug in one to four to create a long blinky display that can be controlled by any 3-5V microcontroller or microcomputer (e.g. Arduino, Raspberry Pi, Particle, and more). The Beam boards communicate via I2C so you only need 2 pins! Build a line of glowing notification text or even animation! Beams can be daisy chained...

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....

If you'd like to get some LEDs or analog strips blinking for your costume, prop or project, but don't want to do any programming, you may want to try out the LED Magician ! It's kinda like a pre-programmed Arduino designed for driving LEDs, and has many built-in effects. Note it doesn't work with 'smart' LEDs such as NeoPixels, DotStars, or other digital addressable LEDs. Best used with 'bare' LEDs or analog LED...

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...
