Opsætningsvejledning

1. Nødvendige komponenter

• Raspberry Pi 3 Model B+ board
• Micro SD card (minimum 8GB, Class 10 recommended) with an operating system installed (e.g., Raspberry Pi OS)
• 5V/2.5A or 5V/3A USB power supply with a micro USB connector
• HDMI cable and a display (monitor or TV)
• USB tastatur og mus
• Ethernet cable (optional, for wired network connection)

2. Preparing the Micro SD Card

1. Download the desired operating system image (e.g., Raspberry Pi OS) from the official Raspberry Pi webwebsted.
2. Use an imaging tool (e.g., Raspberry Pi Imager, Etcher) to write the OS image to your Micro SD card.
3. Skub sikkert Micro SD-kortet ud af din computer.

3. Tilslutning af eksterne enheder

Follow these steps to connect your peripherals to the Raspberry Pi:

1. Insert the prepared Micro SD card into the card slot on the underside of the Raspberry Pi.
2. Connect your USB keyboard and mouse to the USB ports on the Raspberry Pi.
3. Connect one end of the HDMI cable to the HDMI port on the Raspberry Pi and the other end to your display.
4. (Optional) Connect an Ethernet cable to the Ethernet port for a wired network connection.
5. Finally, connect the micro USB power supply to the power input port on the Raspberry Pi. The device will power on automatically.

Betjeningsvejledning

1. First Boot and Initial Setup

Upon connecting power, your Raspberry Pi will begin to boot. You should see the boot sequence on your connected display. If you are using Raspberry Pi OS, you will be guided through an initial setup wizard to configure settings such as:

• Country, language, and timezone
• Ændring af standardadgangskoden
• Opretter forbindelse til et Wi-Fi-netværk
• Opdatering af software

Følg anvisningerne på skærmen for at fuldføre opsætningen.

2. Grundlæggende brug

Once the initial setup is complete, you can start using your Raspberry Pi. The desktop environment is similar to a traditional computer. You can:

• Browse the internet using the pre-installed web browser.
• Write code in various programming languages (e.g., Python, Scratch).
• Adgang files and folders using the file leder.
• Install new software from the Raspberry Pi OS repository.
• Connect to other devices via Bluetooth or USB.

3. Nedlukning

To prevent data corruption, always shut down your Raspberry Pi properly before disconnecting power. Do not simply unplug the power cable.

• Graphical Interface: Click on the Raspberry Pi icon in the top-left corner, then select "Shutdown" and choose "Shutdown" or "Reboot".
• Terminal: Open a terminal window and type sudo shutdown -h now to shut down, or sudo reboot at genstarte.

Opretholdelse

1. Softwareopdateringer

Regularly update your Raspberry Pi's operating system and installed software to ensure security, stability, and access to the latest features.

• Åbn et terminalvindue.
• Type sudo apt update and press Enter to refresh the package list.
• Type sudo apt full-upgrade and press Enter to install all available updates. Confirm with 'Y' if prompted.

2. Fysisk pleje

• Keep the Raspberry Pi in a clean, dry environment, away from dust and moisture.
• Avoid exposing the board to extreme temperatures.
• Handle the board by its edges to avoid touching components, especially when powered on.
• Consider using a protective case to prevent accidental damage.

Fejlfinding

1. Ingen skærmoutput

• Ensure the HDMI cable is securely connected to both the Raspberry Pi and the display.
• Check if the display is set to the correct HDMI input source.
• Verify that the Micro SD card has a valid operating system image and is properly inserted.
• Prøv et andet HDMI-kabel eller en anden skærm.

2. Power Issues (Red LED not lit or flickering)

• Ensure you are using a compatible 5V/2.5A or 5V/3A power supply. Underpowered supplies can cause instability.
• Check the power cable and micro USB connector for damage.
• Avoid using long or thin USB cables, as they can lead to voltage drop.

3. Wi-Fi/Bluetooth Connectivity Problems

• Ensure the Wi-Fi/Bluetooth module is enabled in the Raspberry Pi OS configuration.
• Check for correct Wi-Fi password entry.
• Move the Raspberry Pi closer to the wireless access point.
• Sørg for, at der ikke er fysiske forhindringer eller interferenskilder.
