Development of a Compact and Accurate Auto-Update Digital Clock with Real-Time Location Display using Organic Light Emitting Diode and Crystal Oscillator

Abstract

Research has been going on for a lengthy time on digital clocks but with restraints to auto-updating based totally on location. The objective of the paper is to produce a portable and accurate auto-update digital watch (clock) that shows the real time and the current location of the user with the aid of crystal oscillator to generate clock pulses which interfaced with the GPS modules with organic light-emitting diode (OELD). The system was able to automatically update the co-ordinate of locations whenever the user moves from one place to another, It also auto-update time whenever the battery is removed and reinserted or when switched OFF and then switch ON after sometime. It also eliminate the stretch associated with time adjustment whenever the battery is down and replaced or when the watch is switched OFF and then ON. It performed satisfactorily and as a result, the system can be adapted and integrated to the new technology of modern watch as it can be adopted by the user to locate his/her position at any point in time.
