ABSTRACT
This project is to develop a password door security
system using microcontroller and can be further enhance for more
advance functions. Remote control keypad
detector cordless phone models (Model: HPD100RF).
This model function remote uses radio frequency
medium for transmitting
data to the reciever and microcontroller circuit. The main objectives are to familiarize with the concepts and functions
of PIC16F877A and also to design a security PIC-based programming code.
This system uses
keypad as user’s input interface and LCD display as output regarding to user’s
input. The LCD display will shows the password symbols and desired words like
short notices or messages. In order to change or remove the messages, the
program coding can be modified and reload it to PIC. When the password input
wrongly for three times, the system will shut down to fulfill the security
purpose. For advance functions, this system will integrated with a speaker
which human sound can be generated followed by the words shown in display. The
users will feel convenience when using this product since its functions is easy
and flexible.
