ABSTRACT
The bell system of Philippine Science High School Western Visayas is vital to the proper transition of classes. The bell system indicates the start and the end of one period to the other. Without the bell system, overlapping of class periods would occur often. This will reduce the optimum potential the lessons that can be taught within a class period. These overlapping of class periods should be eliminated because this would hinder room for more expansive learning of the students.
The existence of microcontrollers allows the possibility of programming circuitries to perform automated functions such as automated bells. Microcontrollers could help eliminate the school’s problem about the overlapping of class periods.
This study explores the feasibility of creating a program for a microcontroller that will contain instructions for a prototype that will automate the bell ringing of the bell system for optimum efficiency of the class periods.
The devices used were an Atmel 8051 Training module-1 and an AT89C4051 microcontroller. The microcontroller was programmed with the use of an All Universal programmable encoded in Assembly Language.
The results of the study showed fabrication of an Automated Bell Ringer prototype for the Philippine Science High School was possible. The program for the microcontroller that would automatically activate the bell system was successfully completed. The bell ringer-prototype showed no errors with their function and was successfully installed to the bell system of Philippine Science High School.
