A project that controls model trains by feeding analog PWM power directly to the rails. Uses Adafruit's motor shield. It hopes to do Automatic Train Control one day.
Without a serial connection, there is no way to ask the ATC system what its status is. How are switches thrown? How fast are trains traveling, and how is their speed changing?
