PERANCANGAN JAM WAKTU SHOLAT REALTIME BERDASARKAN GPS RECEIVER BERBASIS MIKROKONTROLER ARDUINO

Abstract

Prayer is an obligation for every Muslim that must be carried out at a specified time. The design of the realtime prayer time clock based on the Arduino microcontroller aims to make it easier to find out the prayer time in real terms based on the clock and the accurate coordinates of the location with the Hashb Auqot as-Shalâh formula. This prayer time clock uses several modules, namely: 1) RTC as a timer, 2) GPS receiver to receive coordinate data and UTC time, 3) Bluetooth as a communication medium with remote settings that uses an Android Smart Phone to manage text information, ihtiyâth, display and murottal, 4) micro-SD card adapter as murottal file reader stored in micro-SD, and 5) Dot Matrix Display (DMD) P10 as the output media displaying running text.
