4. 운영
4.1 기본 작업
Once the operating system is installed and configured, your Raspberry Pi is ready for use. You can interact with it via the connected keyboard, mouse, and display, similar to a traditional desktop computer. The Raspberry Pi OS provides a graphical user interface (GUI) for ease of use.
4.2 소프트웨어 설치 및 업데이트
Software can be installed via the graphical "Add/Remove Software" utility or through the command line using `apt` commands (e.g., `sudo apt update`, `sudo apt install [package_name]`). Regular updates are recommended to ensure system stability and security.
4.3 GPIO Usage
The 40-pin GPIO header allows for advanced projects involving physical computing. You can connect various sensors, actuators, and other electronic components to control them programmatically using languages like Python.
Refer to the official Raspberry Pi documentation for detailed guides on GPIO programming and hardware interfacing.
5. 유지관리
- 소프트웨어 업데이트: Regularly update your operating system and installed software packages to receive the latest features, bug fixes, and security patches. This can typically be done via the terminal using `sudo apt update` followed by `sudo apt upgrade`.
- 전원 관리 : Always use a stable and sufficient power supply (5.1V / 2.5A) to prevent unexpected shutdowns or data corruption. Avoid disconnecting power without properly shutting down the operating system first.
- SD 카드 관리: Micro SD cards can wear out over time. Regularly back up your data and consider using high-quality, durable cards. Avoid frequent power cuts to minimize the risk of SD card corruption.
- 물리적 환경: Keep the Raspberry Pi in a cool, dry, and well-ventilated area. Avoid exposing it to extreme temperatures, humidity, or dust. Consider using a protective case.
6. 문제 해결
- 전원/부팅 안 됨:
- Ensure the power supply is correctly connected and meets the 5.1V / 2.5A specification.
- Check the Micro SD card for proper insertion and ensure it has a valid operating system image.
- Look for the red power LED (PWR) to be steadily lit and the green activity LED (ACT) to flash during boot.
- 디스플레이 문제:
- Verify the HDMI cable is securely connected to both the Raspberry Pi and the display.
- 디스플레이가 올바른 입력 소스로 설정되어 있는지 확인하세요.
- 네트워크 연결 문제:
- For wired Ethernet, check the cable connection and router status.
- For Wi-Fi, ensure the correct network name (SSID) and password are entered in the OS settings.
- Restart your router and the Raspberry Pi.
- 주변 장치가 응답하지 않음:
- 다른 USB 포트에 USB 장치를 연결해 보세요.
- For Bluetooth devices, ensure they are in pairing mode and correctly configured in the OS.
