ATmega64 Morse Code Generator

Microprocessor project developed using AVR Assembly language and simulated using Proteus.

---

Project Overview

This project implements a Morse code generator using an ATmega64 microcontroller.

The system receives predefined user-selected characters and continuously displays their Morse code representation using an LED output and waveform display.
