3. Arahan Persediaan

1. Pemasangan Pemandu: If using Windows, you may need to install the CP210X USB to UART bridge VCP driver from Silicon Labs. Search online for "CP210X USB to UART bridge VCP driver" to find the official download.
2. Sambung ke Komputer: Use the provided USB cable to connect the KEYESTUDIO V4.0 Development Board to your computer. The board can be powered via this USB connection.
3. Pasang Arduino IDE: Download and install the official Arduino Integrated Development Environment (IDE) from the Arduino webtapak (www.arduino.cc/en/software).
4. Pilih Papan dan Pelabuhan: Buka IDE Arduino. Pergi ke Alatan > Papan dan pilih "Arduino Uno". Kemudian, pergi ke Alatan > Pelabuhan and select the serial port corresponding to your connected board (it will typically show "Arduino Uno" or the CP2102 chip).
5. Kuasa Luaran (Pilihan): For projects requiring more power or standalone operation, connect an AC to DC adapter (7-12V) to the power jack on the board.

4. Arahan Operasi

1. Load an Example Sketch: Dalam IDE Arduino, pergi ke File > Cthamples > 01.Asas > Berkelip to open the classic LED blink sketch.
2. Verify Code: Click the "Verify" button (checkmark icon) in the Arduino IDE to compile the code and check for errors.
3. Kod Muat Naik: Click the "Upload" button (right arrow icon) to upload the compiled sketch to your KEYESTUDIO V4.0 Development Board. The RX and TX LEDs on the board will blink during the upload process.
4. Perhatikan Operasi: Once uploaded, the onboard LED (connected to digital pin 13) should begin to blink, indicating successful operation.
5. Experiment with Projects: The board can be used with various sensors, actuators, and shields. Refer to Arduino tutorials and project guides for detailed instructions on specific applications.

5. Penyelenggaraan

• Storan: Store the board in an anti-static bag when not in use to prevent damage from electrostatic discharge.
• Pembersihan: Gunakan kain lembut dan kering untuk membersihkan papan. Elakkan menggunakan cecair atau pembersih yang kasar.
• Pengendalian: Handle the board by its edges to minimize contact with components and prevent static discharge.
• Bekalan Kuasa: Sentiasa pastikan vol yang betultage (7-12V for external power) is applied to avoid damaging the board.

6. Penyelesaian masalah

• Board Not Detected:
  • Ensure the CP210X USB to UART bridge VCP driver is correctly installed (refer to Setup Instructions).
  • Cuba port USB atau kabel USB yang berbeza.
  • Restart your computer and the Arduino IDE.
• Ralat Muat Naik:
  • Verify that the correct board type ("Arduino Uno") and serial port are selected in the Arduino IDE.
  • Periksa semua pendawaian untuk sambungan longgar atau litar pintas.
  • Pastikan tiada program lain yang menggunakan port bersiri.
• No Power/LEDs Not Lighting Up:
  • Check USB cable connection or external power supply.
  • Pastikan sumber kuasa menyediakan vol yang betultage.
