Setup Tasks: the arduinos show up with the same USB name and device ID. This can cause some issues if you are using more than one panel. I've had DCS switch back and forth depending on how the game loads up the panels. The comment from Dakor91 on March 4th, 2017 in the following link provides a solution by editing the boards file and inputing in a unique VID, PID, and device name: https://github.com/MHeironimus/ArduinoJoystickLibrary/issues/14

Materials: Push button switch, 1P1T, momentary (qty 20) Toggle switch, 1P2T, momentary (qty 5) Rotary switch, 1P12T, (qty 2) [only using 5 pins, switch has locking ring to prevent rotation past desired setting] Encoder w/ push button KY-040 (qty 4) Arduino Due (qty 1) metric poop ton of stranded wire

Code: code works but I haven't gone back to clean up the comments. may have some out dated comments from when I was using a diode matrix to add more push buttons.
