Abstract :
Time is very important in every aspect of life. It is the quantity that measures the progressive existence of life and events. This paper presents a microcontroller PIC16F887 based digital clock which displays time progressively in real-time using liquid crystal display. To achieve the aim of this research, various relevant literatures were reviewed to note areas of advancement. It was found that liquid crystal display is the best component to display time. The constructed device is reliable and portable. It displays time accurately in numerical form on the 16*2 LCD. The portable clock makes use of the 24-hour timing format. This clock is monolingual as it uses English language only. The power supply is principally a 9V battery. This 9V is regulated by an integrated circuit LM7805, offering 5V to the microcontroller. The microcontroller is the central processing unit of this device. It is responsible for computations and logic manipulations to be displayed by the output LCD. The microcontroller was programmed using C language. C language is robust and powerful for operations and scientific applications. The designed clock was tested on Proteus software at simulation stage. The physical components were implemented on a breadboard to ascertain workability, and the design was implemented by soldering on vero-board as final construction. This digital clock is functional, portable and reliable. It is a viable solution to keeping record of time at every event or stage.
