In the previous video we controlled a physical signal on the layout, using a signal symbol on the switchboard and connect it to a DCC address to control the hardware as well as connect it to an internal block signal for the switch logic.
If following the internal signals is all the ‘eye candy’ you need there could have been an easier way. Internal block signals can be connected to a DCC address themselves, there’s no need to add additional signal symbols in that case.
But if you want to have a bit more control on the logic of when a signal changes aspect, then such additional signal is the way to go, because they have a Trigger tab as well as a Conditions tab, where logic functions can be built to control the signal’s aspects.
The video shows both examples.
