I have made model rail level crossing lights which uses reed switch positioned on track to sense magnetic field of coming train and then LEDs are flashed.
It uses three 555 timer - monostable, bistable and astable circuit.
Now, I want gate or barrier at railway crossing to automatically drop when train comes and automatically lift up when the train leaves.
Any idea how to implement this ??
