6. Maintenance

To ensure the longevity and optimal performance of your Yahboom Micro:bit Robot Car Kit, follow these maintenance guidelines:

• Cleaning: Keep the robot free from dust and debris. Use a soft, dry cloth to wipe surfaces. Avoid using liquids or harsh chemicals.
• Battery Care: Charge the lithium battery using the provided USB cable. Do not overcharge or completely drain the battery. Store the robot with a partially charged battery if not in use for extended periods.
• Connections: Periodically check all screw connections and cable plugs to ensure they are secure. Loose connections can affect performance.
• Storage: Store the robot in a cool, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting

If you encounter issues with your robot car, consider the following troubleshooting steps:

• Robot Not Powering On: Ensure the lithium battery is fully charged and correctly connected. Check the power switch on the expansion board.
• Robot Not Responding: Verify that the Micro:bit board is securely inserted into the expansion board. If using IR control, ensure the remote's plastic gasket is removed and it is aimed correctly. For APP control, confirm Bluetooth is enabled on your device and the app has necessary permissions.
• Movement Issues: Check motor connections and ensure wheels are properly attached. If a wheel is not moving, inspect its wiring.
• Programming Errors: Double-check your code for any syntax errors or logical flaws. Refer to the online tutorials for guidance. Re-downloading the program to the Micro:bit can resolve many issues.
• Micro:bit Display Issues: If the Micro:bit's LED matrix is not displaying correctly, ensure the board is properly seated and the program is loaded.
