🎵 Arduino/ESP32 Buzzer – Senbonzakura

Play Japanese music with a buzzer on Arduino/ESP32
This project plays the song 千本桜 (Senbonzakura) through a passive buzzer, compatible with both Arduino and ESP32 boards.
You can try it directly on Wokwi without any physical hardware!

❤️ Why I made this

Because I heard this and felt it funny Senbonzakura so I wanted to turn it into a buzzer version to both practice and share the joy with others.
