Hello Everyone, I have an nscale layout and I am controlling the kato/unitrack 2-wire turnouts using a 8 channel relay board, pushbuttons, and an arduino to throw the turnouts. This works fine. I have dwarf signals I would like to use. Currently they are connected to the arduino and they change via software which is fine. However I would like to save on pins and would like to attach the signals somehow to the turnout or the relay board. Now the relay board shuts off as to not burn up the solenoid on the turnout. Anyone have any ideas on how I can do this and provide pictures/schematics? Thanks in advance!
