Use ir sensors to detect an object which would be the car. So 2 sensors and 4leds

    Fairly easy to use a simple state machine and a switch - case, if it where longer I would look at it differently but this is a pretty short and simple thing

    Let me suggest you consider hall-effect sensing rather than optical interruption here.  It could be both more reliable and unobtrusive, maybe.  Probably easier to implement.  Perhaps you could glue PMs to the bottom of your model cars.

     

    Though, maybe you could glue a mirror to the bottom of a car just as easily. . .

     

    This is juicy.  Please elaborate a little more upon your application, SVP.
