4. Persediaan

Follow these steps to set up your DFRobot UNO R3 board for the first time:

4.1. Software Installation (Arduino IDE)

  1. Muat turun versi terkini Arduino IDE daripada Arduino rasmi webtapak (www.arduino.cc/en/software).
  2. Install the Arduino IDE on your computer by following the on-screen instructions.

4.2. Menghubungkan Lembaga

  1. Connect one end of the provided USB cable to the USB B-type connector on your DFRobot UNO R3 board.
  2. Sambungkan hujung kabel USB yang lain ke port USB yang tersedia pada komputer anda.
  3. The board's power LED should illuminate, indicating it is receiving power.

4.3. Pemasangan Pemandu

The DFRobot UNO R3 board uses the ATMega16U2 chip for USB-to-serial communication. Most modern operating systems (Windows, macOS, Linux) will automatically detect and install the necessary drivers when the board is connected for the first time. If prompted, allow the system to install the drivers.

4.4. Selecting Board and Port in Arduino IDE

  1. Buka Arduino IDE.
  2. Pergi ke Alatan > Papan dan pilih "Arduino Uno".
  3. Pergi ke Alatan > Pelabuhan and select the serial port corresponding to your DFRobot UNO R3 board. This will typically appear as a COM port on Windows (e.g., COM3, COM4) or a /dev/ttyUSB* or /dev/ttyACM* device on Linux/macOS.

5. Arahan Operasi

Once your DFRobot UNO R3 board is set up, you can begin programming and interacting with it.

5.1. Uploading Your First Sketch

  1. Dalam IDE Arduino, pergi ke File > Cthamples > 01.Asas > Berkelip. This will open a new window with the Blink examplakaran le.
  2. Ensure the correct board and port are selected (as described in Section 4.4).
  3. Klik pada Muat naik button (right arrow icon) in the Arduino IDE toolbar. The IDE will compile the sketch and upload it to your board.
  4. Upon successful upload, the onboard LED (usually connected to digital pin 13) should start blinking.

5.2. Memberi Kuasa kepada Lembaga

The DFRobot UNO R3 can be powered in several ways:

  • Kuasa USB: Connect the board to your computer via the USB cable. This is suitable for most projects.
  • Bekalan Kuasa Luaran: Connect a 7-12V DC power adapter to the power jack. This is recommended for projects requiring more power or when the board is not connected to a computer.
  • VIN Pin: Provide regulated 7-12V DC power directly to the VIN pin.

Caution: Do not supply more than 12V to the power jack or VIN pin, as this can damage the board.

6. Penyelenggaraan

To ensure the longevity and proper functioning of your DFRobot UNO R3 board, follow these maintenance guidelines:

  • Tangani dengan Berhati-hati: Avoid dropping the board or subjecting it to excessive force.
