This document describes a term project to create a digital watch for a mosque that displays the prayer time schedule, temperature, and date. It includes the schematic designs created in Proteus, embedded C code created in Code Vision AVR, and a 5V power supply PCB design created in Eagle Cad. The project features an ATmega32 microcontroller, 7-segment displays, shift registers, decoders, an RTC, temperature sensor, and LCD display. Simulations were created in Proteus to test the designs. The document discusses some limitations and possibilities for future implementation to reduce costs.

LACKINGS & FUTURE IMPLEMENTATION
In our project we weren't able to reduce the port less utilization to obtain the low cost
prayer time showing & we are hopeful to solve that with the future implementation by
that reference with schematic design & codes.
