2. Kurulum

2.1 Gerekli Bileşenler

• Raspberry Pi 4 Model B (8GB) board
• Official Raspberry Pi USB-C Power Supply (5.1V, 3A) or equivalent
• MicroSD card (minimum 8GB, Class 10 recommended) with Raspberry Pi OS installed
• Micro HDMI to HDMI cable (x2 for dual display)
• USB klavye ve fare
• HDMI girişli monitör veya TV
• (Optional) Ethernet cable for wired network connection

2.2 MicroSD Kartın Hazırlanması

1. Download the Raspberry Pi Imager software from the official Raspberry Pi webalan.
2. Insert your MicroSD card into a card reader connected to your computer.
3. Open Raspberry Pi Imager, select your desired operating system (e.g., Raspberry Pi OS Full), and choose your MicroSD card.
4. Click "Write" to install the operating system onto the MicroSD card. This process will erase all existing data on the card.
5. Once the writing process is complete, safely eject the MicroSD card from your computer.

2.3 Çevre Birimlerini Bağlama

Before applying power, connect all necessary peripherals:

• MicroSD Kart: Insert the prepared MicroSD card into the card slot on the underside of the Raspberry Pi.
• Görüntülemek: Connect one or two Micro HDMI to HDMI cables from the Raspberry Pi's Micro HDMI ports to your monitor(s).
• Klavye ve Fare: Connect your USB keyboard and mouse to the USB 2.0 or USB 3.0 ports.
• Ağ (Opsiyonel): For a wired connection, plug an Ethernet cable into the Ethernet port.

2.4 Açma

Once all peripherals are connected, plug the USB-C power supply into the Raspberry Pi's USB-C power port. The Raspberry Pi will automatically power on and begin the boot process. The red power LED will illuminate, and the green activity LED will flash during boot.

3. Kullanım Talimatları

3.1 İlk Önyükleme ve İlk Yapılandırma

On the first boot, Raspberry Pi OS will guide you through an initial setup wizard. This includes setting your country, language, timezone, creating a new password, connecting to Wi-Fi, and updating software. Follow the on-screen prompts to complete the setup.

3.2 Desktop Environment

After initial setup, you will be presented with the Raspberry Pi OS desktop environment. This functions similarly to other desktop operating systems, allowing you to browse the web, edit documents, program, and more.

3.3 Bağlantı

• Wifi: Connect to a wireless network using the network icon in the top-right corner of the desktop.
• Bluetooth: Pair Bluetooth devices via the Bluetooth icon in the top-right corner.
• Ethernet: If an Ethernet cable is connected, the Raspberry Pi will automatically establish a wired network connection.

3.4 GPIO Başlığı

The 40-pin GPIO (General Purpose Input/Output) header allows you to connect and control various electronic components and sensors. Refer to the official Raspberry Pi documentation for detailed information on GPIO programming and usage.

4. Bakım

4.1 Yazılım Güncellemeleri

Regularly update your Raspberry Pi OS to ensure optimal performance, security, and access to the latest features. Open a terminal and run the following commands:

sudo apt update
sudo apt full-upgrade -y
sudo reboot

4.2 Soğutma

The Raspberry Pi 4 can generate significant heat under heavy load. For sustained performance, especially in enclosed spaces or demanding applications, consider using a heatsink or an active cooling solution (e.g., a fan) to prevent thermal throttling.

4.3 Safe Shutdown

Always shut down your Raspberry Pi properly to prevent data corruption on the MicroSD card. You can do this via the desktop menu (Menu > Shutdown > Shutdown) or by opening a terminal and typing:

sudo shutdown -h now

Wait for the green activity LED to stop flashing before disconnecting power.

5. Sorun Giderme

• Görüntü Çıkışı Yok:
  • Ensure Micro HDMI cables are securely connected to both the Raspberry Pi and the monitor.
  • Monitörün doğru giriş kaynağına ayarlandığından emin olun.
  • Try a different Micro HDMI cable or monitor.
  • Ensure the MicroSD card has a valid operating system installed.
• Power Issues (No LEDs, No Boot):
  • Confirm you are using a compatible 5.1V 3A USB-C power supply.
  • Check the power cable and connection.
  • Try a different power supply if available.
• Wi-Fi/Bluetooth Bağlantı Sorunları:
  • Ensure the Wi-Fi/Bluetooth module is enabled in the Raspberry Pi OS settings.
  • Check for correct network credentials.
  • Raspberry Pi'yi kablosuz erişim noktasına daha yakın bir yere taşıyın.
  • Sinyali engelleyen herhangi bir fiziksel engelin olmadığından emin olun.
• Yavaş Performans:
  • Check for excessive heat and consider adding a cooling solution.
  • Ensure your MicroSD card is a high-speed (Class 10 or higher) card.
  • Gereksiz uygulamaları kapatın.
  • Bir yazılım güncellemesi gerçekleştirin.
