Hi All
I have a question.
What I am trying to achieve is this:
I have a model train signal that has a LED which can change between red and green.
What I want to do is change the signal manually with a switch from the default position of Red to Green. Once the train goes past the signal, the signal changes to Red automatically and stays at Red until I manually change it to green.
Does anyone know of a circuit on how to do this? Would I need a relay or something else ? Is there a schematic out there or has someone done this previously? I have looked at the home.cogeco.ca/~rpaisley4/CircuitIndex.html website but could not find anything that has a manual change from Red to Green and a automatic back to Red.
Cheers
Shelton.
