Some knowledge of electrical switching may be needed here. Esstially what I need is for the lamp to be on when the path is complete and off when the path is not complete. Triggers dont appear to cut it.
It would also be helpful to my students if the completed path were to glow or some indication of the path.
I think this is beyond my expertise, sure hope someone can help me out here.
FYI, I have also posted this elsewhere seeking assistance...
