  4. Push the clip back down to secure the connection.

2. Connecting A USB Camera

If you prefer using a USB camera, the setup is slightly different.

Steps to Connect:

  1. Plug the USB camera into one of the USB ports of the Raspberry Pi Zero.
  2. If you’re using the original model, you may need an OTG cable to adapt the USB connection.

Testing The Camera Connection

Now that you’ve connected your camera to the Raspberry Pi Zero, it’s time to test the connection.

1. For The Raspberry Pi Camera Module

Open a terminal and type the following command to capture a photo:

bash
raspistill -o image.jpg

This will save a photo named “image.jpg” in the current directory.

2. For A USB Camera

If you’re using a USB camera, you can use the fswebcam package to capture images.

Steps to install and use fswebcam:

  1. Install fswebcam by running:

bash
sudo apt-get install fswebcam

  1. Capture an image using the command:

bash
fswebcam image.jpg

This command will take a picture and save it as “image.jpg”.

Using The Camera For Projects

Once your camera is connected and tested, you can use it for various exciting projects.

1. Home Surveillance System

Creating a security system is an excellent way to utilize your camera setup. You can use motion detection libraries to capture images or video clips when movement is detected.

Key Components:

  • Store captured images on the Pi or upload them to the cloud.

2. Time-Lapse Photography

You can create stunning time-lapse videos using the Raspberry Pi Camera.

Tips for Time-Lapse:

  • Use the raspistill command in a loop with a delay.
  • Combine images into a video using the ffmpeg library.

bash
for i in {1..100}; do raspistill -o image$i.jpg; sleep 5; done

This command captures 100 images at intervals of 5 seconds.

3. Stream Video Online

Streaming live video is made easy with a setup like this.

Options for Streaming:

  • Use software like motion for real-time streaming to your local network.
  • Utilize FFmpeg for pushing live streams to platforms like YouTube.
