4. Operating Instructions

The LAFVIN Smart Home IoT Learning Kit supports both graphical programming and traditional Arduino C++ programming. The included tutorial provides various projects to guide you through operating the different modules.

4.1. Basic Control and Monitoring

Utilize the provided code examples to control the kit's components. For instance, you can program the system to:

• Turn LEDs on/off based on sensor input or app commands.
• Control the fan for temperature regulation.
• Operate the servo motors to open/close doors or windows.
• Monitor environmental conditions using the DHT11 (temperature/humidity), soil humidity, and water level sensors.
• Detect motion with the photoelectric interrupt module.

4.2. App-Based Control

The kit supports app-based control, allowing you to interact with your smart home model wirelessly. Follow the tutorial to set up the mobile application and connect it to your R3 board via Bluetooth or Wi-Fi (if applicable to your specific R3 board version). The app interface typically provides controls for lights, fans, doors, and displays sensor data.

5. Maintenance

To ensure the longevity and optimal performance of your LAFVIN Smart Home IoT Learning Kit, follow these maintenance guidelines:

• Cleaning: Gently wipe the wooden components and electronic modules with a dry, soft cloth. Avoid using liquids or abrasive cleaners, as they can damage the components.
• Storage: Store the kit in a cool, dry place away from direct sunlight, moisture, and extreme temperatures. Keep components organized in their original packaging or a suitable storage container to prevent loss or damage.
• Handling: Handle electronic components with care to avoid electrostatic discharge. Always ensure the power is disconnected before making or changing any wiring connections.
• Battery Care: If using batteries, remove them from the battery case when the kit is not in use for extended periods to prevent leakage.

6. Troubleshooting

If you encounter issues with your kit, consider the following common troubleshooting steps:

• Power Issues: Ensure the R3 board is correctly powered via USB or the barrel jack. Check battery connections if using the battery case.
• Connection Problems: Verify all wiring connections are secure and correctly inserted into the appropriate pins on the R3 and V5 boards. Loose connections are a common cause of malfunction.
• Code Upload Failure: Confirm that the correct board type and serial port are selected in the Arduino IDE. Reinstall drivers if necessary.
• Component Malfunction: Test individual components with simple, isolated code examples to determine if a specific module is faulty.
• Software Errors: Double-check your code for syntax errors or logical flaws. Refer to the tutorial and online Arduino resources for debugging tips.
