About Wi-FI ESP32 learning journey

StudyInEsp32 is an open-source project by xuhongv designed to help beginners learn native SDK development for the ESP32 microcontroller (WiFi + BT modules). It provides a comprehensive collection of over 27 example projects, covering a wide range of topics from basic GPIO and timers to more advanced features such as Wi-Fi provisioning (SmartConfig, AirKiss), TCP/UDP networking, Bluetooth speaker, camera capture and upload to cloud, RFID reading, sensor interfaces (DHT11, SHT20), LED control (WS2812, PWM), OTA updates, and HTTPS file operations. Each example is a standalone project with precompiled binaries for quick testing. The repository is actively maintained with 505 stars and 206 forks, licensed under Apache-2.0.
