Introduction: LED Martrix（alter）
In this instructable I'm going to rewrite website ( https://www.instructables.com/Arduino-8x8-LED-Matrix/ ), I will show you another way to perform the LED Martrix.
8*8 LED matrix with MAX7219
Step 1: Circuit
The Connections goes as follows -
CLK => Arduino digital pin10
CS => Arduino digital pin9
DIN => Arduino digital pin8
GND => Arduino digital GND
VCC => Arduino external 5v power supply
Step 2: Type the Code
The code is inside this pack
Step 3: Generate Paterns
You can design this pattern by this website
Type it there (image)
You can copy and paste the string in the sample code from the previous step to generate custom patterns.
