Arduino Basics
===============

This section contains 9 fundamental projects that teach you how to control each peripheral on the ESP32-S3 board using Arduino. You'll start with simple GPIO output and progressively learn to use I2C sensors, SPI displays, SD cards, cameras, and audio.

Each project is self-contained and includes complete source code that you can compile and upload directly.
