This Arduino sketch creates a fire animation on a 8x8 LED matrix module controlled by a MAX72XX

These modules are fairly inexpensive (~$6 US) and only require a few pins to control 64 LEDs arranged in a 8x8 matrix.
A common demo is create a flame or fire-like animation on the device.
I wasn't able to find one that worked with the monochromatic MAX72XX controlled devices so made this.
A search on the standard retailers will find devices that should work, typically using a description similar to:
MAX7219 Dot Led Matrix MCU Control LED Display Module
