8x8 Matrix LED Display

8x8 LED matrix display

What exactly is better than an individual LED? countless LEDs! An enjoyable option to make a little display is to utilize an 8x8 matrix or a 4-digit 7-segment display. Matrices such as these tend to be 'multiplexed' - so to regulate 64 LEDs you may need 16 pins. That is most pins, and there are motorist potato chips just like the MAX7219 that will get a handle on a matrix obtainable but there's plenty of wiring to create and so they use a huge amount of space. Here at Adafruit we feel your discomfort! In the end, wouldn't it be awesome if you could control a matrix without a lot of wiring? This is where these adorable Light-emitting Diode matrix backpacks may be found in. We all of them in two flavors - a mini 8x8 and a 4-digit 0.56" 7-segment. It works completely using matrices we stock in Adafruit store and then make including a bright small display insignificant.

The matrices use a motorist chip that does all heavy-lifting available: obtained a built in time clock so they really multiplex the display. They use constant-current drivers for ultra-bright, constant color (the pictures above tend to be photographed at the dimmest setting-to stay away from overloading our camera!), 1/16 step screen dimming, all via a straightforward I2C program. The backpacks come with address-selection jumpers to help you connect to four mini 8x8's or eight 7-segments (or a mix, such as for instance four mini 8x8's and four 7-segments, etc) on a single I2C coach.

This product system comes with:

Some soldering must attach the matrix on the backpack but its quite simple to-do and only takes about 5 minutes.
