ABSTRACTThis project presented a digital code locker.
It was designed with microcontroller that accepts input password, and stores
data for the purpose of providing a quality access control or electronic
security. Security has been a major
challenge to humanity. No matter how organized and peaceful a society is, there
are always one or more scrupulous persons who always have the desire to steal
from people or bridge people’s privacy. Due to this menace, this project
utilized keypad, buzzer, pic16f84 controller, crystal oscillator and other
passive and active components put together using top down and bottom- up
approach to achieve the project aim and objectives. The keypad was arranged in
matrix form and the whole circuitry was executed using modular technique. The
values of the components used
were gotten through mathematical formulas, datasheets, circuit intuition and
brainstorming. The use of microcontroller helps to realize most of the
difficult task through coding. The c programming code helps to solve the design
problem logically and keeps mathematic to a minimum in order to foster a good
intuitive understanding of circuit design and behavior. The project was
simulated in Protues 8.3 professional and was tested OK. Both the hardware and software implementation
was successful. At the end, the problem of intrusion which has led to
the loss of valuable documents or property can drastically reduced to the
barest minimum with the implementation of this project.
