Electrical Engineering Portfolio

Welcome! This repository documents my hands-on engineering projects completed while exploring electronics, embedded systems, circuit design, and PCB development.

My goal is to build practical engineering skills through designing, simulating, documenting, and improving real hardware projects rather than only studying theory.

Current Projects

ATmega328P-Smart-Assistive-Navigator PCB

⭐ Latest Project

This project documents the complete design of a custom two-layer printed circuit board (PCB) for an ATmega328P-based assistive navigation hardware platform.

SAN - (Smart Assistive Navigator)

An Arduino-based prototype that assists visually impaired users by detecting nearby obstacles and providing feedback using ultrasonic sensors and vibration/audio alerts.

Adaptive Smart Light System

An automatic lighting system that adjusts LED brightness according to ambient light levels using an LDR sensor.

Smart Gas Leakage System

A gas monitoring and alert system that detects gas levels and responds using LEDs, LCD messages, and a buzzer alarm.

More projects and experiments will be added over time as I continue learning.

Why I Started This Repository

I created this repository to document my progress while exploring electronics and embedded systems.

Right now I’m mainly focused on:

• sensor-based systems
• automation concepts
• Arduino projects
• circuit simulation
• learning how different components interact in a complete system

I’ll continue updating this repository as I build more projects and improve my understanding.
