| - | Generates a square wave of the specified frequency (and 50% duty cycle) on a pin. A duration can be specified, otherwise the wave continues until a call to [[arduino:advanced io:NoTone]](). The pin can be connected to a piezo buzzer or other speaker to play tones. | + | Generates a square wave of the specified frequency (and 50% duty cycle) on a pin.
