Theory Of Operation

1. The entrance to the parking garage will have a display that informs of the available parking spaces.

2. This display is updated from a circuit that is connected to infrared proximity sensors.

3. The sensors will detect when a motor vehicle enters or exits the parking garage. This information is then relayed to a microcontroller inside an Arduino.

4. The Output will then be displayed on a Seven segment display.
