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.
