🎵 Arduino BeatSync

Arduino BeatSync is a music visualization project that plays a song while synchronizing LED light patterns to its beat. Using audio splicing software, I analyzed and isolated key beat points from a track, then programmed the Arduino to flash LEDs in sync with the music. The result is a simple yet captivating fusion of sound and light.

🔧 Features

Plays a custom melody or spliced song via a piezo buzzer

LEDs flash and pulse in sync with the beat

Adjustable timing for perfect rhythm alignment

Easy to modify for different songs or lighting setups

🧠 How It Works

Audio Splicing: The song was processed using audio splicing software to identify the beats and note durations. These were converted into millisecond intervals for Arduino timing.

Arduino Control: The Arduino plays tones through a piezo buzzer using the tone() function while controlling LEDs to match the rhythm.

Beat Synchronization: Each beat triggers a light flash on the LED, creating a real-time visual representation of the music.
