Use Raspberry Pi to power a RBG Matrix Display to show BART Arrival times.

- 3x $25 Medium 16x32 RGB LED matrix panel
- 1x $25 5V 10A switching power supply
- 1x $35 Raspberry Pi 3 - Model B+
Follow these instructions by the maker of the RaspberryPi RGB Matrix Library. I've edited the defaults of base.py to assume you're using 3x 16x32 boards. Inspect base.py to change these defaults, or via flags. It's predictable.
