A discovery project about data design within the confinements of a 24x24 single color led matrix. I'm using the current time as the dataset.
MAX7219 IC's are driving each of the 9 8x8 matrices. This library is driving the chips.
Since the focus of this project is the way the time is displayed, I haven't bothered adding a real time clock (RTC) module yet. But I have written the code so that it can be added easily.
