PIC 16F84 to LCD interface

:shock: :?: I just don't understand what kind of alarm system you are talking about.. burgler, rain alarm, fire alarm ?? :?:
Anyway one thing i understand that you want to use PIC16F84 with LCD interface.
see the link below it is an example how you can interface PIC16f84 to LCD using 4 bits mode so that you will have rest of the pin left for the sensors and mabe buzzres for your alarm system.

another link which explains about LCD interface- i think one of the best
