Arduino Getting Started

New to Arduino ESP32 development and looking for a quick start? We have prepared a comprehensive Getting Started Tutorial for you.

• Section 0: Getting to Know ESP32
• Section 1: Installing and Configuring Arduino IDE
• Section 2: Arduino Basics
• Section 3: Digital Output/Input
• Section 4: Analog Input
• Section 5: Pulse Width Modulation (PWM)
• Section 6: Serial Communication (UART)
• Section 7: I2C Communication
• Section 8: SPI Communication
• Section 9: Wi-Fi Basics
• Section 10: Web Server
• Section 11: Bluetooth
• Section 12: LVGL GUI Development
• Section 13: Comprehensive Project

Note: This tutorial uses the ESP32-S3-Zero as a reference example, and all hardware code is based on its pinout. Before you start, we recommend checking the pinout of your development board to ensure the pin configuration is correct.

Setting Up Development Environment

1. Installing and Configuring Arduino IDE

Please refer to the tutorial Installing and Configuring Arduino IDE to download and install the Arduino IDE and add ESP32 support.

2. Other Tips

1. In the Board Manager, select the "ESP32S3 Dev Module" model for development.

   

2. The ESP32-S3-DEV-KIT-N8R8 uses the ESP32-S3 native USB interface, not a UART-to-USB bridge. For serial communication:

   • The printf() function can be used directly;

   • To use the Serial.println() function, additional configuration is required: Enable the "USB CDC On Boot" option in the IDE's Tools menu, or declare an HWCDC object in your code to handle USB serial communication.
