Space Invaders Clock

Inspired by [GeckoDiode][1] (Instructables) and [smooth_jamie][2] (Instructables), I had to take up the challenge and build a version of my own.

Case design is original and is designed to work with a MAX7219 LED dot matrix module. Arduino sketch is based off [smooth_jamie][2] original work. I improved the RTC logic and fixed various LED hex byte arrays for minutes and animations that did not display correctly. In addition, the Alien Space Ship now completes the cast of characters.

[LED Matrix Editor][3] is a great tool to help create and troubleshoot matrix displays.
