The Music Box - Remote-Controlled Musical Device

Overview

The Music Box is a remote-controlled device that plays random musical notes using a Pico-Sensor kit and Python. The project integrates hardware components, including a buzzer, LED, and RGB lights, to create an engaging and interactive musical experience.

Features

• Remote-controlled musical note generation
• LED and RGB light synchronization with music
• Play/Pause functionality for user control
• Randomized note playback for variety
• Wireless interaction using a Pico microcontroller

Hardware & Materials

• Raspberry Pi Pico
• IR Remote Control
• Buzzer
• RGB LED Strip
• Standard LED
• Resistors and Wiring
• Power Supply

Software Dependencies

Ensure you have the following Python libraries installed:

pip install machine utime neopixel

Implementation Steps

1. Turn on the device using the remote's Play/Pause button.
2. The red LED indicates the device's status: ON (active) or OFF (paused).
3. Each button press plays a random note via the buzzer and triggers an RGB light show.
4. The red LED turns on and off in sync with playback.

Code Snippet (Example)

from machine import Pin, PWM
from utime import sleep
import random

buzzer = PWM(Pin(12))
tones = {"C4": 262, "D4": 294, "E4": 330, "F4": 349, "G4": 392, "A4": 440, "B4": 494}

def play_note():
    note = random.choice(list(tones.values()))
    buzzer.freq(note)
    buzzer.duty_u16(30000)
    sleep(0.5)
    buzzer.duty_u16(0)

while True:
    play_note()
    sleep(1)

Testing

• Signal Transmission: Verified that button presses successfully transmit signals to the Pico microcontroller.
• Play/Pause Functionality: Ensured accurate toggling of the device.
• LED & RGB Response: Checked synchronization with remote button presses.

Future Improvements

• Add a feature to allow users to assign specific musical notes to remote buttons.
• Implement a setting mode for user-defined sound effects.

Conclusion

The Music Box successfully combines hardware and software to create an interactive musical experience. The integration of the Pico-Sensor kit with Python demonstrates the seamless interaction between embedded systems and software programming.
