==============
Arduino project showing scrolling text on a MAX7219-based 8x8 LED matrix.
Requirements:
* LedControl library for controlling the hardware
* a nice bitmapped monospaced font of size 8x8 or smaller
* imagemagick for creating a binary font file
* xxd utility to convert a binary font file into a C-style include file.
To build a new font:
* run 'make' to convert the font (check how it looks by opening font.png)
* update source code to reflect the effective height and width of the glyphs
To run:
* make sure a MAX7219-based 8x8 LED matrix is connected to the arduino
* make sure the LedControl constructor matches your hardware connections (for DIN, CS, CLOCK)
* compile and upload the .ino file into an Arduino (arduino nano for example)
