Abstract
This paper presents the design of a digital clock, while providing an easy and convenient means of updating the time, and/or any other message that may be displayed. The aim was to design and also introduce a user-friendly update mechanism through creating input methods – using a 4x4-numeric keypad for data input, establishing communication protocol with Bluetooth and output method using a liquid crystal display. The design incorporated both hardware and software in achieving this aim, with the hardware consisting of LCD, LEDs, RTC, HC-05 Bluetooth module, and a 4x4-numeric keypad. The software is handled by a ubiquitous microcontroller – ATmega16A, programmed in C++, as well as a generic HC-05 Android Bluetooth Application for data input (in addition to the hardware means of update – keypad). Hence, this design introduced convenience (user-friendliness) as compared to clocks which are manually updated. The overall design had percentage accuracy and error of 99.17 and 0.8 respectively.
