Main Conclusions and Recommendations

This project was successful.  We completed the design and verification of all the hardware and software components according to our specifications.  There were several issues that arose during this project and all of them were overcome. 

Major recommendations for this project would be to install the alarm into a car with the additional protection circuitry that guards against voltage spikes when the car is started.  

Another recommendation is to transfer the circuit onto a printed circuit board so that it can be installed into a small remote.  The remote casing can be purchased for a small price at Radio Shack. 

The sensors should be extended to include the rear car doors if it is a four-door vehicle.  This is easily done by adding another OR gate or using a 4 input OR gate into the external interrupt pin in of the pic16F84.
