Animated preview of the working digital clock system.

This project features a fully functional Digital Clock system designed using an AVR Microcontroller (ATmega32). The system maintains an accurate 24-hour time format (HH:MM:SS) and outputs the data to an LCD display (LM016L). It combines precise firmware timing with a professional hardware simulation in Proteus.

• Precise Timekeeping: Utilizes internal Microcontroller Timers to ensure 1-second accuracy for real-time tracking.
• 24-Hour Format: Automatically handles time overflows (60 seconds to 1 minute, 60 minutes to 1 hour, 24 hours to reset).
• Interactive Controls: Includes hardware reset and manual adjustment capabilities via push-buttons.
• Visual Interface: Displays real-time clock and date data on a 16x2 character LCD.

• Hardware: ATmega32 Microcontroller (AVR Architecture).
• Software/Firmware: C Language (main.c).
• Simulation Tool: Proteus Design Suite.

The following flowchart represents the operational logic of the system, including initialization, time incrementing, and display refreshing.

The system follows a structured execution path to ensure real-time accuracy:

1. Initialization Phase:

   • I/O Ports: Configures Port B and Port D as outputs for the LCD data and control lines.
   • LCD Setup: Initializes the LM016L screen in 16x2 mode and clears the display.
   • Variables: Sets the initial time values.

2. The Main Loop (Infinite):

   • Time Tracking: The system monitors for a 1-second trigger (via Timer or Delay).
   • Increment Logic:
     • Seconds increment by 1.
     • If Seconds == 60, they reset to 0 and Minutes increment by 1.
     • If Minutes == 60, they reset to 0 and Hours increment by 1.
     • If Hours == 24, the clock resets to 00:00:00.

3. Display Update:

   • The microcontroller converts time values to ASCII and updates the LCD display with the formatted HH:MM:SS string.

• main.c: The core C source code containing the timing logic.
• digital_clock.pdsprj: The Proteus simulation file for hardware verification.
• Clock_report[1].pdf: Detailed technical documentation.
• flowchart.png: Visual logic flowchart of the firmware.
• Animation.gif: Animated preview of the working system.

1. Simulation: Open digital_clock.pdsprj in Proteus and click the 'Play' button.
2. Firmware:
   • Open main.c in an AVR compiler (e.g., Microchip Studio).
   • Compile the code to generate the .hex file.
   • Load the .hex file into the ATmega32 component within Proteus.
