ESP32 Study Material & Example Codes

This repository is a comprehensive collection of study materials, example codes, and notes for learning and experimenting with the ESP32 microcontroller. It is designed for students, hobbyists, and developers who want to explore various features of the ESP32, including GPIO, analog/digital I/O, interrupts, timers, PWM, touch sensors, flash memory, and more. Future updates will include Web Server, LoRa, BLE, and other advanced topics.

📝 Notes

• All code examples are written in C++ for PlatformIO.
• Each .cpp file is self-contained and demonstrates a specific feature.
• Use PlatformIO in VS Code for easy building and uploading.
• Check the troubleshooting.cpp and this README for common issues and tips.

---

🚀 Getting Started

1. Install PlatformIO in VS Code.
2. Clone this repository:

   git clone https://github.com/yourusername/esp32Funcs.git
   

3. Open the project in VS Code.
4. Connect your ESP32 board and select the correct COM port.
5. Build and upload any example from the src/ folder.
