Technical Details:

Hardware:

• ESP32: Acts as the core microcontroller for NFC data reading and Wi-Fi communication.

• PN532 NFC Module: Reads data such as album IDs or track information from NFC tags.

• HC-SR04 Ultrasonic Sensor: Enables interactivity by detecting proximity and triggering actions like switching tracks.

• Projector: Displays animations created in Ventuz Designer in real time.

Software:

Arduino (ESP32 Firmware):

• Reads NFC tag data.

• Sends commands and data to a Python server via Wi-Fi.

• Uses ultrasonic sensor data for interactivity (e.g., switching tracks).

Ventuz Designer:

• Visualizes track information, artist bios, and other metadata with animated effects.

• Integrates JSON data for real-time updates.

Python Server:

• Handles requests from ESP32.

• Integrates Spotify API for fetching album and track details.

• Generates and updates JSON files for Ventuz Designer.

1. API Integration:

   • Spotify API: Fetches track metadata, album details, and playback information.

   • OpenAI API: Generates artist bios and additional descriptive content.

2. Workflow:

   • NFC tag data (e.g., album ID) is read by the ESP32.

   • The data is sent to the server, where it is processed using the Spotify API.

   • A JSON file is generated with information like track name, artist bio, and album name.

   • Ventuz Designer uses the JSON data to create real-time animations projected onto a screen.

Key Features:

1. Real-Time Interaction:

   • Immediate visualization of NFC tag data through Ventuz animations.

2. Dynamic Data Integration:

   • Updates JSON data dynamically based on scanned NFC tags.

3. User Interactivity:

   • Ultrasonic sensor enables user interaction for actions like switching tracks or activating animations.

4. API-Powered:

   • Spotify and OpenAI APIs provide comprehensive metadata for songs and artists.
