Arduino Uno Led Matrix Project (2014)

This is a very old project of mine from 2014 ;)

It works by reflecting the buffer variable to the LEDs with Timer ISR at a specified frequency.

you can draw anything you want with set_pixel or set_screen_frame functions

• 24 x 8 resolution...

• 3 shift registers for full row... (79HC595)

• 1 transistor array for driving leds... (ULN2003A)

• Contains various animations and sprites...

• Turkish font characters...

• Text scrolling feature...
