Sound sensor display a real-time waveform on a web server

Project:
1. Read Analog Data: Capture sound sensor readings using the analog pin (A0 for Wemos D1 Mini, you can use ESP32).
2. Process Data: Normalize and smooth the readings.
3. Send to WebSocket/Webserver: Use an ESP-hosted web server to stream real-time data.
4. Visualize Data: Display a waveform using Chart.js or Canvas in JavaScript.

KY-038 Pin Wemos D1 Mini
VCC 3V3
GND GND
AO A0
How It Works:
• The ESP8266 reads the analog sound sensor data.
• A WebSocket connection streams real-time values.
• The web page uses a canvas to draw a waveform.
