A fun way to make a small display is to use an 8x8 matrix or a 4-digit 7-segment display. Matrices like these are 'multiplexed' - to control 64 LEDs you need 16 pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you, but there's a lot of wiring to set up and they take up a ton of space. After all, wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these lovely LED matrix backpacks come in.

The matrices use the constant-current drivers for ultra-bright, consistent color, 1/16 step display dimming, all via a simple I2C interface. These 1.2" matrix backpacks come with three address-selection jumpers so you can connect up to eight 1.2" 8x8's together (or a combination, such as four 1.2" 8x8's and four 7-segments, etc) on a single I2C bus.

Features:

8 rows and 8 cols LED matrix
Driven by HT16K33 chip
Access to I2C communication pins
Occupy less IO ports of microcontrollers
Easy connection and available for more experiment extensions

Parameters:

Input voltage: 5V
Rated input frequency: 400KHZ
Input power: 2.5W
Input current: 500mA

Wire it Up:

Connect the SCL pin to Analog A5, SDA pin to Analog A4 port; Connect VCC pin to 5V port, GND pin to GND.

Sample Code:

Below is an example code, you can upload it to Arduino IDE.

Download Arduino IDE
Install Arduino Driver
