Design Of An Automatic Bell Warning System For Prayer Times In A Net Centric Computing Lab

Abstract

The development of science and technology has been increasing rapidly, providing convenience in everyday life. Various household appliances and office work tools use electronic devices to ease the works, including bell warning systems for prayer times. The system notifies the people when the times for prayer comes. The warning systems used presently have not operated automatically. The research aimed to design and implement a series of automatic warning bell system for prayer times, that sent a notification to the telegram. It used Arduino Mega 2560 as the data processor. The result found that the tool, equipped with an RTC, a Dfplayer, a loud-speaker, and an Ethernet Shield, worked satisfactorily by sending a notification to the Telegram.

Transformation of Prayer Time Schedules: from A Static-Passive to A Dynamic-Variative Perspective

“…36 There are also those who design a digital time schedule through Arduino Mega 2560 which when entering prayer time can be immediately accepted for Telegram users. 37 Please note that in preparing a digital prayer time schedule, it will have higher accuracy if the clock is integrated with an internet connection or integrated with the Global Positioning System (GPS). If the clock is only controlled manually, then the accuracy level is very low, it must even be calibrated frequently so that the clock displayed matches the day.…”

Design of gas concentration measurement and monitoring system for biogas power plant

“…The installed sensors were the MQ-4 sensor to detect methane gas (CH4), MG-811 sensor to detect carbon dioxide (CO2) gas, MQ-136 sensor to detect sulfide acid gas (H2S), and Thermocouple Type-K to detect the temperature. The sensors sent a signal to the control unit in Arduino Mega 2560 [24]- [25], and then it would be processed and displayed on LCD.…”
