🎼 Musical Floor with Raspberry Pi

This project is a musical floor instrument built using infrared obstacle sensors and a Raspberry Pi.
The floor is designed to look like piano keys, with each key assigned to one sensor.
When a person steps on a key, the Raspberry Pi plays the corresponding note through a speaker.

Additionally, there are two control buttons that allow the user to switch between different instrument modes:

• 🎹 Piano
• 🔔 Bells
• 🎶 Flute
• 🎸 Guitar

⚙️ Components Used

• Raspberry Pi (any model with GPIO support)
• 8 Infrared Obstacle Detection Sensors (IR sensors)
• 2 Push Buttons (for instrument selection)
• Speaker connected to Raspberry Pi
• Jumper wires and breadboard

🎶 How It Works

1. The floor is designed like piano keys, each equipped with an infrared sensor.
2. When someone steps on a key, the sensor detects the movement.
3. The Raspberry Pi processes the signal and plays the correct note based on the selected instrument.
4. Two push buttons allow the user to switch between instrument modes (Piano, Bells, Flute, Guitar).
