[Sudrian Spotlight - NWR No.403 'Thorkell']

I watched all the Sudrian Spotlight videos while having lunch. The plausible backstories are as good as the kitbashing! Do you plan to do the narrow gauge lines too?

[6. 2-aspect signal control from a single GPIO pin]

There would be a direct path from 3.3V to GND through both LEDs and both would be on.

[1. Basic set up]

The advantages will become clear as the tutorials progress. These are the absolute basics to get people going.

 

One example might be interlocking, e.g. you can create a simple program which will not allow a signal to be set to exit a siding when the points are against the train. This is easier to do in software than in hard wired electronics.
