This document discusses using a PDA with GPS capabilities to automatically determine the Qibla direction for Muslim prayers in real-time. It aims to improve upon early manual methods by devising an innovative system where a PDA communicates with an external microcontroller equipped with GPS and a digital compass via Bluetooth. This would allow Muslims to easily obtain their precise Qibla direction and prayer times anywhere in the world through their PDA. The document outlines the objectives and technical components involved, including how GPS works and the functions of the PDA and external device.
