This is a basic LED matrix library for an Arduino with a 74HC595 shift register.
The library was designed to be used for a matrix of 4x4 or below. Example code was written for a 3x3 matrix using the setup as shown below.
Parts List:
- Pro Micro 5V 16Hz x1
- 74HC595 shift register x1
- 330 ohm resistor x3
- LEDs x9
