Qibla Finder and Sholat Times Based on Digital Compass, GPS and Microprocessor

To performing Sholat, Muslims around the world are required to pay attention to the requirements of Sholat, such as; determining the direction of the Qibla (Kaaba) and the time of Sholat. In this research will be made a real time Qibla Finder and Sholat Times named Q-Bot Ver3 to help Muslims find a Qibla direction and Time of Sholat anywhere. This Qibla Finder and Sholat Times are developed with robotic technology based on Digital Compass, GPS and Microcontroller. To determine the Qibla direction and Sholat times, latitude and longitude data form GPS module processed used spherical triangle trigonometry method, while the compass module used to show the Qibla direction. Moreover, this system has a buzzer which can sound if the device facing to the Qibla. This system is reliable and accurate in determining the Qibla Finder and Sholat Times. Thus, the advantage of the system is can correct the Qibla of Masjid and can help blind people to facing Qibla around the world.
