Arduino projects and demos that use the PC speaker.

/eyes/ - Plays "Eyes on Me" from Final Fantasy VIII. Uses 8 LEDs to show which notes are played.

/gongjinou/ - Plays "Gong Jin Ou," the Qing national anthem. Uses 5 LEDs as a pitch analyzer.

/rain/ - Plays "Rain" from Xian Jian. Uses a serial shifter and digital LED to display note names as they are played. The decimal point indicates sharps.

You can’t perform that action at this time.
