Welcome to my Arduino Projects Repository!
This repository is a documentation of my hands-on journey into the world of embedded systems using Arduino. What began as a curiosity to understand how electronics work has transformed into a passion to build real-world applications—from simple LED blinking to complex systems like automatic doors and communication protocols.
The purpose of this repo is to take you from the fundamentals of microcontroller programming to real-world applications. Each project is designed to help you understand key concepts while building something practical, laying the foundation for future projects in electronics, IoT, and robotics.
As I continue my journey, new projects and resources will be added to expand on concepts and explore new areas of electronics. Let’s get started and build something amazing!
This repository contains a collection of structured mini-projects, covering:
- Arduino programming basics
- Digital and analog input/output
- Sensors and actuators
- Timers and displays
- Practical system design and prototyping
Each project includes:
- Code
- Documentation
- Images
- Circuit Diagrams
All of this is designed to support learning and reproducibility.
