I’ve added a YouTube video of the Arduino-based throttle test to the Throttles page.

This evening I was successful in driving one of my PORTRAM trams on a loop of track, powering it with an Adafruit Motor Shield mounted on an Arduino Uno microcontroller. The code was basically the Motor Shield’s “DCMotorTest” example code with modified timings.

I caught some video of it running, which I’ll post on the Throttles page as soon as I get a chance to upload it.
