 Changed code that runs on Raspberry Pi to drive the HT16K33. Arduino not required for this. It does work, but could use some improvement, where it draws lines more than just a dot for the aileron/elevator intersection. Implemented by adding horizontal and vertical lines, with dimmed LEDs, but they flicker terribly at the slow testing speed.

 Bought a small HDMI screen to use with the Raspberry Pi 4. It comes with short HDMI-to-HDMI cables, but it is also not very useful, because it uses some of the GPIO pins as well. I need the GPIO pins for the Rotary Encoder.

+====== Arduino As Joystick Interface ======
+I haven't been working with Arduinos for a while. Recently set up MSFS 2020 with PMDG 737 and decided that controlling thrust and thrust reversers better than the default, or using my X52 was worth pursuing.
+I know that there are 3 kinds of Arduinos which appear to Windows as a Joystick:
+  * Arduino Leonardo
+  * Arduino Micro
+  * Arduino Micro Pro
+It appears I purchased an Arduino Leonardo (which easier-to use pins), and a 3-pack of Arduino Micro Pro compatibles, both in 6/2021.
+^Requirement^Comment^
+^Power Required|5V, but an upstream regulator may need 6.2V|
+==== Notes ====
+Rasperry Pi's require 3.3 V. To convert between 5V components, there is an IC which allows interfacing either up or down.
