Back in September in the post Control center for the staging yard I briefly mentioned the circuit I built to turn each of the sidings in the staging yard ON and OFF simultaneously with the routing of the turnouts. In the post I want to give more details on this. I'm running DCC so why do I need to do this ? At this point I've not really gotten my head around the JMRI / Panel Pro stuff and I would like to do some automation of some parts of the layout in the future.
The smaller board is a diode matrix and the larger one contains the latching circuits and relays.
To make this work with an Arduino I will need to build a special shield board with the necessary relays, circuits to drive the relays, and terminal strip connections. When I get a chance to work on that, I'll be sure to share it in a post.
The diode matrix is something that also is worthy of more explanation and that will be another future post.
