6. Betjening
The Arduino Nano 33 BLE Sense Rev2 is programmed using the Arduino IDE. You can write your own sketches (programs) or use existing examples to get started.
- Writing a Sketch: Open a new sketch in the Arduino IDE. The basic structure includes `setup()` for initialization and `loop()` for repetitive tasks.
- Uploading Code: After writing your code, click the 'Upload' button (right arrow icon) in the Arduino IDE. The IDE will compile your code and upload it to the board. Ensure the correct board and port are selected.
- Using Onboard Sensors: Utilize the installed libraries to read data from the IMU, microphone, temperature, humidity, light, color, and pressure sensors. Refer to the library examples for specific usage.
- BLE Communication: Implement Bluetooth Low Energy (BLE) functionality to enable wireless communication with other BLE-enabled devices. This allows for data exchange, remote control, and integration into mobile applications.
- TinyML Applications: Explore TinyML examples and tutorials to deploy machine learning models directly onto the board for edge computing, enabling intelligent decision-making without cloud dependency.
7. Vedligeholdelse
- Hold tør: Protect the board from moisture and extreme temperatures to prevent damage to electronic components.
- Håndteres med forsigtighed: Avoid applying excessive force to the board or its components. Static electricity can damage sensitive parts; handle the board by its edges.
- Rengør forsigtigt: If cleaning is necessary, use a soft, dry brush or compressed air to remove dust. Avoid liquids or abrasive materials.
- Korrekt strømforsyning: Brug altid en stabil strømforsyning inden for det angivne volum.tage range (4.5-21V via VIN, or 5V via USB) to prevent overvoltage eller undervoltage problemer.
8. Fejlfinding
- Board Not Recognized: Ensure the USB cable is securely connected and functional. Check if the correct board support package and drivers are installed in the Arduino IDE. Try a different USB port or cable.
- Upload Errors: Verify that the correct board and serial port are selected in the Arduino IDE. Check for syntax errors in your code. Ensure no other program is using the serial port.
- Sensorfejl: Confirm that the relevant sensor libraries are installed and correctly included in your sketch. Check wiring if external sensors are used.
- BLE Connectivity Issues: Ensure Bluetooth is enabled on both the Nano 33 BLE Sense Rev2 and the device you are trying to connect to. Verify that the BLE library is correctly implemented in your code.
- Strømproblemer: If the board is not powering on, check the power source. Ensure the input voltage er inden for det angivne område.
