MU/TH/UR LED Matrix

If you opted to include the MU/TH/UR LED Matrix in your PS-85 build, you can set it up to display a simple blinking pattern similar that seen in the Alien movies.

The CharliePlex LED Matrix Bonnet is well documented over on Adafruit's website if you want to explore more functionality.
