Abstract

Muslims are obligated to perform prayer five times a day. One of the conditions to perform the prayer is to face towards Qibla direction which in Islam it is point towards Kaabah in the city of Mecca. Therefore, in this project, a Sajadah (praying mat) that has the function to show the direction of Qibla has been designed. Using the combinations of embedded system, microcontroller, digital compass, gps module and LED indicator, the Sajadah have the function to show the correct direction of Qibla from any place in the world. The Sajadah which called e-Sajadah have five LEDs (green/red) that will tell users if he/she has the right direction of Qibla. This device finds the direction of Magnetic North through digital compass (HMC588L) and gives output heading which will be sent to the microcontroller. Arduino Uno R3 is used which it is a microcontroller board based on ATmega328P microcontroller that are using Arduino software to write the algorithm. With the GPS module readings of the user’s current location, Qibla direction is determined using solution of spherical triangle. The solution involves longitude and latitude of user’s current location and Kaabah. The methods of determining the deviation of distance if there is one degree deviation from the exact angle towards Kaabah also were studied.
