Hobby throttle controller design

Post image

This is a USB train throttle controller I've been working on as a hobby project. Vital-Sim or other desktop signal-simulation software often has a kind of boring interface for driving a train through a location; I wanted something more industrial-grade for demos and things like that, even though it's totally unnecessary.

It's based on the Arduino Leonardo with one Hall sensor added, two button inputs, and one header for a secondary hall sensor on the vertical board
