Microcontroller-based school bell system for the College of Engineering, DMMMSU-MLUC

Abstract

This study aimed to develop an accurate reliable synchronized clock system for the operation of the College of Engineering, Don Mariano Marcos Memorial State University – Mid La Union Campus (DMMMSU-MLUC), City of San Fernando, La Union. It was a school bell system that was meant to synchronize class change and thus, bells were made available on every floor of the Engineering building, and that they all rang at the same time during class change. The Descriptive Research design was used in the study in gathering data on the actual problems relating to the absence of a bell system at the College of Engineering, DMMMSU-MLUC as well as the features included in the study. Rapid Application Development design was also used in the design and development of the prototype of the Microcontroller-Based School Bell System for the College of Engineering, DMMMSU-MLUC. Findings showed that Arduino microcontroller, relay module, real-time clock, Liquid Crystal Display, slide switch, pushbutton, and the round bells were the essential components in the design of the device; that the construction of the Microcontroller Based School Bell System for the College of Engineering, DMMMSU-MLUC was conducted using different electronic materials; and that testing of the components and the entire set-up of the device was made possible using different electronic measuring tools and equipment.
