6. Operating Instructions

The LAFVIN ESP32 Robot Smart Car is operated via a WIFI connection, typically through a web interface on your smartphone or computer.

6.1. Connecting to the Robot Car

1. Power on the robot car by ensuring the 18650 batteries are correctly installed in the battery case.
2. The ESP32 module will create a Wi-Fi access point. Connect your smartphone or computer to this Wi-Fi network.
3. Open a web browser and navigate to the IP address provided in the documentation (e.g., 192.168.4.1). This will open the control interface.

6.2. Control Interface and Features

The web interface typically includes directional controls (Forward, Backward, Left, Right, Stop) and options for controlling the integrated camera and auxiliary lighting.

• Real-time Video Stream: The ESP32 camera module allows you to observe the surroundings in real-time directly from the control interface while the car is moving.
• Directional Control: Use the on-screen buttons to navigate the robot car.
• Auxiliary Light Control: Toggle the car's light on or off for improved visibility in low-light conditions.

7. Maintenance

• Keep the robot car clean and free from dust and debris.
• Regularly check all electrical connections to ensure they are secure.
• Store the kit in a dry, cool place when not in use.
• Remove batteries if the car will not be used for an extended period to prevent leakage.

8. Troubleshooting

If you encounter issues with your LAFVIN ESP32 Robot Smart Car Kit, consider the following:

• Car Not Moving / Incorrect Direction:
  • Check all motor connections to the L298N driver. Ensure wires are correctly oriented. Sometimes, motor wires might be reversed, requiring adjustment in wiring or code.
  • Verify battery charge and proper installation.
  • Confirm the motor driver is receiving power.
• ESP32 Not Connecting / No Wi-Fi Signal:
  • Ensure the ESP32 module is powered on.
  • Check the antenna connection.
  • Re-upload the code to the ESP32 module.
  • Verify that the correct board and COM port are selected in the Arduino IDE during upload.
• Arduino IDE Compilation Errors (e.g., `LedCSetup()` not defined):
  • This can occur due to library or ESP32 core version differences. You may need to adjust the code to use compatible functions. For example, replace `LedCSetup()` and `LEDCAttatchPin()` calls with `ledcAttachPin()` and `ledcSetup()` as per your ESP32 core version's requirements. Consult ESP32 documentation for specific function signatures.
• Missing Parts: If any parts are missing upon arrival, please contact LAFVIN customer support immediately.
