Programming and Customization
The ELEGOO Smart Robot Car Kit V4.0 is fully compatible with Arduino IDE, allowing users to upload custom code and expand its functionalities.
- Arduino IDE: Download and install the Arduino IDE from the official Arduino website.
- Install Libraries: Install necessary libraries for the sensors and modules included in the kit (e.g., ultrasonic sensor library, servo library).
- Upload Code: Connect the UNO R3 Microcontroller to your computer via the USB cable. Select the correct board and port in the Arduino IDE, then upload your custom sketches.
- Experiment: Modify existing code examples or write new programs to explore different behaviors and interactions with the environment.
Maintenance
- Cleaning: Gently wipe the robot car and its components with a dry, soft cloth to remove dust. Avoid using liquid cleaners.
- Battery Care: Remove batteries if the robot car will not be used for an extended period to prevent leakage. Use only recommended battery types.
- Component Inspection: Periodically check all connections and physical components for any signs of wear or damage. Tighten loose screws as needed.
Troubleshooting
- Robot not moving:
- Check battery level and ensure they are correctly inserted.
- Verify all motor connections to the Smart Car Shield.
- Ensure the correct code is uploaded to the UNO R3 Microcontroller.
- Sensors not responding:
- Confirm sensor cables are securely connected to the correct pins on the Smart Car Shield.
- Check if the sensor libraries are correctly installed in Arduino IDE.
- App connection issues:
- Ensure the robot car is powered on and within range of your device.
- Verify that the ESP32-WROVER-B Camera Module is correctly configured for Wi-Fi communication.
- Restart both the robot car and your controlling device.
- Infrared remote not working:
- Check the remote control's battery.
- Ensure there is no obstruction between the remote and the robot's IR receiver.
