About the Project

This project creates a simple LED sound visualizer.

As sound increases:

• More LEDs glow
• LEDs “dance” with music or clap sounds

Students can learn:

• Analog sensors
• Sound detection
• LED patterns
• Music visualization
• Arrays in Arduino

About the Project

The sound sensor detects:

• Music
• Clap
• Voice
• Loud sounds

Arduino reads sound intensity and lights LEDs based on sound level.

Low sound → Few LEDs ON
High sound → Many LEDs ON

It looks like a mini music equalizer 🎶

Components Required

• Arduino Nano / Uno – 1
• Sound Sensor Module – 1
• LEDs – 10
• 220Ω Resistors – 10
• Breadboard
• Jumper Wires
