I’ve added a first draft of a Software section to the Switch Machine Controller page. Links are provided to my GitHub pages where the codes can be found.
I’ve added a pair of Fritzing drawings to the Switch Machine Controller page. One is a breadboard drawing to give a rough idea of how I’ll be wiring up an Adafruit Pro Trinket 5V (Arduino-class processor) to a pair of L293D drivers, which together will drive up to 4 KATO single-coil switch machines. I’ve also added a schematic of the design as well. I’m in the process of adding a Software section to that page as well, which I plan to have in place this evening, time permitting.
The Switch Machine Controllers page now has a short video of a successful test of the controller design, using an Arduino Micro and an L293D motor driver chip.
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.
The Track Sensors page has now received a link to my GitHub repository which contains the Arduino codes used to run the track sensor network.
Finally got to the last page of the main topics I had planned from the beginning. This page includes a couple of YouTube videos, one of mine and one recorded by someone else in Japan.
