Thesystem has a user interface that allows the owner to arm and disarm the vehicle with a 4digit code, and if in armed mode ultrasonic sensors will detect if someone has entered thecar. An alarm will then sound, as well as notify the owner of the car via cell phone, andtake pictures of the criminal.  Table of Contents Project Abstract:..........................................................................................................1Table of Contents........................................................................................................2List of Tables and Figures...........................................................................................3Project Features/Objectives........................................................................................4Analysis of Competitive Projects................................................................................5Concept/Technologies.................................................................................................6Project Architecture....................................................................................................7Flowcharts...................................................................................................................8Final Division of Labor...............................................................................................9Bill of Materials........................................................................................................10Gantt Chart................................................................................................................11Appendices................................................................................................................12Appendix A: PICBasic Code..............................................................................13Appendix B: Camera Code.................................................................................24  List of Tables and Figures   Table 1: Division of Labor..................................................................................................9Table 2: Bill of Materials..................................................................................................10Figure 1: System Level Block Diagram..............................................................................7 Figure 2: User Interface Code Flowchart............................................................................8 Figure 3: Gantt Chart........................................................................................................10   Project Features/Objectives     Arming and Disarming – The car owner will be able to arm or disarm the systemthrough the LCD and keypad interface with a four digit code. While disarmed,none of the peripherals will be activated. In armed mode, the system willconstantly check the A/D input from the sensor to detect a break-in.     Detecting car entry – Using an ultrasonic sensor to determine the presence of someone in the vehicle. Because the user interface would be located in the door of the car and a person has to physically get into the car to trigger the alarm, this willallow the car owner to arm and disarm the system without setting the alarm off.     Alarm – The system will use a “quiet” alarm, one that will relay a message and beclear and audible to whoever is in the immediate vicinity of the car, but will notdisturb others who are far away.    Pictures – When the car alarm is activated, a camera located in the vehicle willbegin immediately snapping pictures of the interior. This can be used at a latertime to identify the thief.    Cell phone interfacing – When the alarm is triggered, the system will send a textto the user’s phone indicating that a break-in is occurring.    Powered independently of car circuitry – The entire system is run off of batteriesthat are independent of the car battery. This will ensure that the car battery is notdrained and that tampering with the internal circuitry of the car will not affect thesystem.
