A building has 12 parking spaces. The owner of the car wants to know if there's an open space by looking at the "LED parking lot lights" displayed outside the building. In addition, the car owner wants to know when three adjacent spaces are open as he/she does not want anyone to park next to their car. Normally, this person parks at the end of a large parking lot to avoid any scrapes or scratches. The system must have one logic indicator to activate if three adjacent spaces become open. The "LED parking lot lights" must also display the number of available parking spaces using seven segment displays.
