Custom parts and enclosures

Controller enclosure (test fitting)

I modeled the different parts in Tinkercad to see how they'd fit and build the case around them.

Final enclosure

The final enclosure for the Arduino-powered controller. The cover didn't fit because I forgot to account for the round screw areas, so I had to trim them with a Dremel.

I used yellow for the model for easier visibility while editing, but the final product was 3D printed in black.

Schematics

Adruino controller - schematic

The final schematic (not 100% sure on the resistor values though)
Schematic

Arduino controller - breadboard

The final circuit breadboarded. Note that the resistor values might be off. Also, the 1x4 keypad doesn't exist in Fritzing, so I used normal buttons to approximate them.
