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.
