| Résumé : |
This project presents the development of a digital prayer times display and control system
designed for mosque environments, integrating modern technologies to enhance the
worship experience. The system consists of a central controller application and remote
display units, enabling real-time and customizable presentation of daily prayer times.
Built using the Qt framework and C++ programming language, the system leverages
the capabilities of both TCP and UDP socket communication to ensure reliable and
efficient data transmission. Raspberry Pi devices serve as display units due to their
compact form, low power consumption, and continuous operational capabilities. The
interface offers flexibility and adaptability to meet the specific requirements of various
mosques, including features such as a countdown to the next prayer, automatic Adhan
playback, and receiving and displaying images over the network. This work bridges
academic learning with real-world application, demonstrating how embedded systems
and network technologies can support religious practices and community organization
in a modern and interactive manner. |

This project presents the development of a digital prayer times display and control system
designed for mosque environments, integrating modern technologies to enhance the
worship experience. The system consists of a central controller application and remote
display units, enabling real-time and customizable presentation of daily prayer times.
Built using the Qt framework and C++ programming language, the system leverages
the capabilities of both TCP and UDP socket communication to ensure reliable and
efficient data transmission. Raspberry Pi devices serve as display units due to their
compact form, low power consumption, and continuous operational capabilities. The
interface offers flexibility and adaptability to meet the specific requirements of various
mosques, including features such as a countdown to the next prayer, automatic Adhan
playback, and receiving and displaying images over the network. This work bridges
academic learning with real-world application, demonstrating how embedded systems
and network technologies can support religious practices and community organization
in a modern and interactive manner. |
