Like mentioned in the title, I need to design a parking lot counter. Problem is that I have no enter/exit input, instead I have sensor placed on each lot, which will activate if the lot is occupied. The system would consist of 8 areas, each having 8-19 lots and own separate display (either green/red or 7-segment), so I need binary output of the amount of occupied lots.
Anyone have any idea how this could be made? I've been searching net for hours but came up with nothing.
