Step-by-Step Guide to Blink an LED with the XIAO ESP32S3

Follow these steps to write and upload your first Arduino sketch using the Arduino IDE:

1. Download and Install Arduino IDE

Visit the Arduino website and download the latest stable version of the Arduino IDE for your operating system (Windows, macOS, or Linux). Install the software and launch it.

2. Add the ESP32 Board Package

To program the XIAO ESP32S3, you will need to add the ESP32 board definitions to Arduino IDE:

• Go to File → Preferences.
• In the "Additional Boards Manager URLs" field, paste the following URL: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
• Click OK to save the preferences.

3. Install the ESP32 Board

• Navigate to Tools → Board → Boards Manager.
• Search for "esp32" in the Boards Manager search bar.
• Install the latest ESP32 package.

4. Load the Blink Example

• Open File → Examples → 01.Basics → Blink.
• This example program is pre-configured to blink an onboard LED at regular intervals.

5. Select Your Board and Port

• Go to Tools → Board and select XIAO ESP32S3.
• Under Tools → Port, select the correct COM port for your device (usually COM3 or higher).

6. Upload the Program

Click the Upload button in the Arduino IDE toolbar. Once uploaded successfully, the orange LED on the XIAO ESP32S3 will blink at regular intervals.

Congratulations!

You have just programmed your XIAO ESP32S3 to blink its onboard LED. This simple project is a great way to get started with the module and familiarize yourself with the Arduino IDE. From here, you can explore more complex projects leveraging the XIAO ESP32S3?s WiFi and Bluetooth capabilities.
