This kit consists of a camera module, a Micro:Bit board, and a AI lens, allowing users to develop AI-powered projects with visual recognition, object detection, and image processing capabilities.

Hardware Components

Camera Module: 2MP OV7670 sensor with a 1/4 inch lens
 Micro:Bit Board: BBC Micro:Bit V2 or V1.5 compatible
 AI Lens: Custom-designed lens for AI-powered applications

Software Support

The Smart AI Lens Kit is compatible with MicroPython, MakeCode, and Python programming languages.

API and Functions

The kit provides the following APIs and functions:

`ai_lens.take_photo()`: Captures an image using the camera module.
 `ai_lens.detect_objects()`: Detects objects in the captured image using AI algorithms.
 `ai_lens.recognize_faces()`: Recognizes faces in the captured image using AI algorithms.
 `ai_lens.classify_image()`: Classifies the captured image into predefined categories using AI algorithms.

Code Examples

### Example 1: Basic Image Capture and Object Detection

In this example, we will capture an image using the camera module and detect objects using the AI lens kit.

```makecode
import microbit
from ai_lens import

ai_lens.init()

while True:
    image = ai_lens.take_photo()
    objects = ai_lens.detect_objects(image)
    print("Detected objects:", objects)
    microbit.sleep(1000)
```

### Example 2: Face Recognition and Display on Micro:Bit Screen

In this example, we will capture an image, recognize faces, and display the face recognition result on the Micro:Bit screen.

```python
import microbit
from ai_lens import

ai_lens.init()

while True:
    image = ai_lens.take_photo()
    faces = ai_lens.recognize_faces(image)
    if faces:
        microbit.display.scroll("Face detected!")
    else:
        microbit.display.scroll("No face detected.")
    microbit.sleep(1000)
```

### Example 3: Image Classification using AI Lens Kit and Micro:Bit Accelerometer

In this example, we will capture an image, classify the image using the AI lens kit, and use the Micro:Bit accelerometer to detect the device's orientation.

```python
import microbit
from ai_lens import

ai_lens.init()

while True:
    image = ai_lens.take_photo()
    classification = ai_lens.classify_image(image)
    print("Image classification:", classification)
    
    x, y, z = microbit.accelerometer.get_values()
    if x > 500:
        microbit.display.scroll("Device is facing up!")
    elif x < -500:
        microbit.display.scroll("Device is facing down!")
    microbit.sleep(1000)
```
