🔊 Buzzer Sound Principle

• Toggle high/low level to produce sound waves

🎼 Note Frequency Table (C4 octave)

C	D	E	F	G	A	B
262	294	330	349	392	440	494 Hz

💃 Dance Choreography

• Beat sync: each note maps to a motion frame
• LED link: high pitch warm color, low pitch cool color
• Wheel rhythm: sway left/right like dance steps
