Learn how to connect and use the official Raspberry Pi camera module with your Raspberry Pi. From connecting the hardware to installing software, this article has you covered!

To connect a Raspberry Pi camera module to your Raspberry Pi, follow these steps:

Prepare Your Hardware
- Make sure you have a Raspberry Pi and an official Raspberry Pi camera module (the V2 version is recommended as it offers higher resolution and better performance).
- You will also need a suitable power supply, microSD card, USB mouse, keyboard, monitor or HDMI cable, and Ethernet cable or WiFi dongle for internet access.
- If you haven’t already, set up your Raspberry Pi with an operating system (we recommend the latest version of Raspbian).
Connect The Camera Module
- Locate the 15-pin camera connector on the camera module and the corresponding female port on the Raspberry Pi board.
- Insert the camera module into the port with the pins facing downwards, ensuring a secure connection.
Power On Your Raspberry Pi
- Connect the power supply to your Raspberry Pi and the Ethernet or WiFi dongle (if applicable).
- Turn on your monitor or connect an HDMI cable if you are using one.
- Plug in a USB mouse and keyboard, then boot up your Raspberry Pi by inserting the microSD card with the operating system installed.
Install The Camera Software
- Open a terminal window on your Raspberry Pi and update the package list:
```
sudo apt-get update
```
- Install the necessary software for using the camera:
```
sudo apt-get install raspi-config
```
Configure Your Camera Settings
- Open the Raspberry Pi configuration tool by running:
```
sudo raspi-config
```
- Navigate to “Interfacing Options” and select “Camera”. Choose “Enable” if it is not already enabled, then follow the on-screen instructions.
Test Your Camera
- Reboot your Raspberry Pi:
```
sudo reboot
```
- Once it has restarted, open a terminal window and run the following command to test if the camera is working correctly:
```
raspistill -o test.jpg
```
- If everything is set up correctly, a picture will be saved as “test.jpg” in your home directory. You can view it with an image viewer like “feh”:
```
feh test.jpg
```

Run Some Camera Examples

There are many ways to use the Raspberry Pi camera, but here are a few examples to get you started:

Take a photo with the command-line tool raspistill:
```
raspistill -o image.jpg
```
Record a video using the raspivid command:
```
raspivid -o video.h264
```

Use OpenCV, a popular computer vision library, to process camera frames in Python:

import cv2

# Create a VideoCapture object and read from the camera
cap = cv2.VideoCapture(0)

while True:
    ret, frame = cap.read()
    cv2.imshow('Camera', frame)
    if cv2.waitKey(1) == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

That’s it! You have now successfully connected a Raspberry Pi camera module and can start exploring its many capabilities. With the right software, you can use your Raspberry Pi to build all sorts of camera-based projects, from security systems to facial recognition applications.
