Raspberry Pi Camera setup - Mini Project: Build & Apply

Raspberry Pi Camera setup

📖 Scenario: You have a Raspberry Pi and want to take pictures using its camera module. To do this, you need to set up the camera in your Python program and capture an image.

🎯 Goal: Build a simple Python program that sets up the Raspberry Pi camera, captures a photo, and saves it as a file.

📋 What You'll Learn

Create a PiCamera object to access the camera

Set the camera resolution to 640x480

Capture an image and save it as image.jpg

Print a message confirming the photo was taken

💡 Why This Matters

🌍 Real World

Taking pictures with a Raspberry Pi camera is useful for projects like home security, wildlife monitoring, or time-lapse photography.

💼 Career

Understanding how to control hardware like cameras programmatically is important for roles in embedded systems, robotics, and IoT development.

1

Import the PiCamera class and create the camera object

Write the code to import PiCamera from picamera and create a camera object called camera.

Raspberry Pi

# Import PiCamera and create camera object
# Your code here

Hint

Use from picamera import PiCamera to import the camera class, then create an object with camera = PiCamera().

2

Set the camera resolution

Set the resolution property of the camera object to (640, 480).

Raspberry Pi

from picamera import PiCamera
camera = PiCamera()
# Set camera resolution to 640x480
# Your code here

Hint

Use camera.resolution = (640, 480) to set the picture size.

3

Capture and save an image

Use the capture method of camera to take a photo and save it as image.jpg.

Raspberry Pi

from picamera import PiCamera
camera = PiCamera()
camera.resolution = (640, 480)
# Capture and save the image as 'image.jpg'
# Your code here

Hint

Call camera.capture('image.jpg') to take and save the photo.

4

Print confirmation message

Write a print statement that outputs "Photo saved as image.jpg" to confirm the picture was taken.

Raspberry Pi

from picamera import PiCamera
camera = PiCamera()
camera.resolution = (640, 480)
camera.capture('image.jpg')
# Print confirmation message
# Your code here

Hint

Use print("Photo saved as image.jpg") to show the message.
