The Air Drum Kit is a virtual drumming application that turns your webcam into a musical instrument. Using Computer Vision (OpenCV) and Color Tracking, it allows you to play drums in mid-air using any blue object—like a blue marker, a drumstick with blue tape, or even a blue toy.

• Real-time Color Tracking: Uses HSV color filtering to track blue objects with precision.
• Virtual Overlay: Visualizes drum pads (Snare, Kick, Hi-Hat, Toms, Crash) directly on your video feed.
• Visual Feedback: Drums light up with a red tint when struck.
• Low-Latency Audio: Uses Pygame Mixer for responsive sound triggering.
• Menu System: Integrated Main Menu and Credits screen.

To run this project, you need Python 3.x installed on your machine along with a webcam.

Install the dependencies using pip:

pip install opencv-python numpy pygame

Important: For the code to run successfully, your file and folder structure must look exactly like this. The application relies on specific paths to load images and sounds.

1. Connect your webcam.
2. Navigate to the project folder in your terminal.
3. Run the script:

python main.py

4. The application will open in the Main Menu.

This application is tuned to detect BLUE objects.

• Best Results: Use a bright blue marker cap, a blue fidget spinner, or wrap blue electrical tape around a pen/stick.
• Lighting: Ensure your room is well-lit so the camera can distinguish the blue color.

You can tweak the settings inside the air_drum_kit.py file:

• Window Size: Modify WINDOW_WIDTH and WINDOW_HEIGHT (Default: 640x480).
• Color Sensitivity: If your blue object isn't being detected, adjust the HSV values:

BLUE_LOWER_BOUND = np.array([90, 50, 20])
BLUE_UPPER_BOUND = np.array([140, 255, 255])
