Real-Time Clock AVR Project

This project is an AVR-based real-time clock that uses an Atmega 32 microcontroller uses internal 8 Mhz clock, an LCD, a keypad, and a 7-segment display to display time and allow users to set the clock.

Hardware Requirements

• Atmega 32 microcontroller
• LCD Display
• Keypad
• 7-segment display
• Capacitors and resistors
• Breadboard or PCB
• Jumper wires

Software Requirements

• AVR Studio 6
• WinAVR
• Proteus Design Suite (for simulation)

Features

• Real-time clock with hour, minute, and second display
• User can set the time using the keypad
• 7-segment display for clock display
• LCD display for setting display

Setup

• Connect the Atmega 32 microcontroller to the breadboard or PCB.
• Connect the capacitors and resistors as required by the crystal oscillator.
• Connect the LCD display to the microcontroller's PORTC and POTRB pins.
• Connect the keypad to the microcontroller's PORTD pins.
• Connect the 7-segment display to the microcontroller's PORTA pins.
• Connect power and ground to the appropriate pins.

Usage

• Compile the code using AVR Studio 6 and WinAVR.
• Upload the hex file to the Atmega 32 microcontroller.
• Power on the circuit.
• The clock will start running automatically.
• To set the clock, press the '1' button on the keypad.
• Use the keypad to set the hour, minute, and second values.
• The clock will now display the updated time.
