Here's our project for logic circuits class:
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 two 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 two adjacent spaces become open, another logic indicator to activate if three adjacent spaces are open. The "LED parking lot lights" must also display the number of available parking spaces using seven segment displays.
Use IR transmitter/receiver to determine the presence of the car.
Any ideas on how to make the project?
12 Parking Space Problem
Re: 12 Parking Space Problem
Well, you can try to use buttons with toggle checked as a control of parking place – if it is taken or free.
To display state of parking lot you just use inverted state of such button and display it with LED or show all of them with LED matrix.
Your indicator of two adjacent places is a conjunction of NOR between all pairs of parking places. This should be easy and fun.
