ESP32 Learning Journey

This repository documents my hands-on journey into Embedded Systems and Firmware Engineering using the ESP32 and ESP-IDF with The C Programming Language.

The goal is to learn by building. Each project focuses on a specific concept, peripheral, or embedded programming technique while improving my understanding of electronics, real-time systems, hardware debugging, and firmware development.

Rather than creating production-ready applications, this repository serves as a collection of experiments, exercises, and practical projects that help me develop embedded engineering skills.

What I'm Learning

• GPIO and Digital Electronics
• FreeRTOS
• Timers and Scheduling
• Interrupts
• UART, SPI, and I2C
• PWM, ADC, and DAC
• Sensors and Actuators
• Wi-Fi and Bluetooth
• Hardware Debugging
• PCB Design with KiCad
• ESP-IDF Development

Why This Repository Exists

I created this repository to:

• Track my progress in embedded development.
• Document what I learn while working with ESP32 devices.
• Practice firmware engineering concepts through real projects.
• Build a portfolio that reflects my growth as an embedded developer.
• Create a reference for future projects.
