2. Setup

2.1. Software Installation

1. Install Arduino IDE: Download and install the latest version of the Arduino IDE from the official Arduino website (www.arduino.cc/en/software).
2. Add ESP32 Board Support:
   • Open Arduino IDE. Go to File > Preferences.
   • In the "Additional Boards Manager URLs" field, add: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
   • Go to Tools > Board > Boards Manager.... Search for "ESP32" and install the "esp32 by Espressif Systems" package.
3. Install Libraries: Depending on the specific module you are using (e.g., DHT sensor, OLED display), you may need to install additional libraries. Go to Sketch > Include Library > Manage Libraries... and search for the required libraries (e.g., "DHT sensor library", "Adafruit SSD1306").

2.2. Hardware Connection Basics

The ESP32 development board features various pins for connecting external components. Always ensure the board is disconnected from power before making or changing connections.

• Breadboard Usage: The included breadboard allows for solderless prototyping. Components are inserted into the holes, and connections are made using the Dupont cables.
• Power Supply: The ESP32 board is typically powered via the Micro USB cable. Ensure your power source provides stable 5V.
• Pinout: Refer to the ESP32 board's pinout diagram for correct connections. Digital pins (GPIO), Analog-to-Digital Converters (ADCs), and communication interfaces (I2C, SPI, UART) are available.

3. Operating Instructions

3.1. Uploading Your First Program (Blink LED)

A common first step is to upload a simple program to make an LED blink.

1. Connect ESP32: Connect your ESP32 board to your computer using the Micro USB cable.
2. Select Board and Port: In Arduino IDE, go to Tools > Board and select the appropriate ESP32 Dev Module. Then, go to Tools > Port and select the serial port connected to your ESP32.
3. Open Example Sketch: Go to File > Examples > 01.Basics > Blink. This will open a new window with the Blink sketch.
4. Upload: Click the "Upload" button (right arrow icon) in the Arduino IDE. The IDE will compile the code and upload it to your ESP32 board. If prompted, press the BOOT button on the ESP32 board during upload.
5. Observe: After successful upload, the built-in LED on the ESP32 board should start blinking.

3.2. Using Included Modules

The kit includes various modules for diverse projects. Each module requires specific wiring and code. Refer to the official LAFVIN tutorial for detailed instructions and example code for each component.

• OLED Display: Connect via I2C. Used for displaying text, graphics, and sensor data.
• DHT11 Sensor: Connect to a digital pin. Used for reading temperature and humidity.
• PIR Motion Sensor: Connect to a digital pin. Detects motion.
• Relay Module: Connect to a digital pin. Used to control higher voltage devices (exercise caution).
• Resistors & LEDs: Fundamental components for basic circuits and visual feedback.

4. Experiments and Tutorials

The LAFVIN ESP32 Basic Starter Kit comes with a comprehensive tutorial that includes codes and lessons. This tutorial is crucial for learning how to assemble and program the various components of the kit. It will guide you through a series of experiments, from basic LED control to more complex sensor readings and IoT applications.

Important: Please download the official tutorial after receiving your kit. This resource provides step-by-step instructions and example code for each module and experiment.

5. Maintenance

Proper care and maintenance will extend the lifespan of your kit components.

• Storage: Store components in a dry, cool environment, away from direct sunlight and extreme temperatures. The original packaging box () is suitable for storage.
• Handling: Handle electronic components by their edges to avoid touching pins or sensitive areas, which can be damaged by static electricity or oils from your skin.
• Cleaning: Use a soft, dry brush or compressed air to remove dust from boards and modules. Avoid using liquids.
• Power Off: Always disconnect power before making or changing any wiring connections.

6. Troubleshooting

If you encounter issues, consider the following troubleshooting steps:

• Board Not Recognized:
  • Ensure the Micro USB cable is a data transfer cable, not just a charging cable. Some cables only provide power and cannot establish a data connection.
  • Check if the correct USB driver is installed for the ESP32's USB-to-Serial chip (often CP210x or CH340).
  • Verify the correct serial port is selected in the Arduino IDE.
• Code Not Compiling/Uploading:
  • Check for syntax errors in your code.
  • Ensure all necessary libraries are installed.
  • During upload, you might need to press and hold the BOOT button on the ESP32 board, then press the EN (reset) button, release EN, and then release BOOT.
• Component Not Working:
  • Double-check all wiring connections against the tutorial diagrams. Ensure correct polarity for LEDs and other polarized components.
  • Verify the component is receiving adequate power.
  • Ensure the correct code and pin assignments are used for the specific module.
  • Test with a known working component if possible.
• Power Issues: Ensure your power supply is stable and provides the correct voltage (5V for the ESP32 board).
