Esplora

## tone()

#### Description

Generates a square wave of the specified frequency from the Esplora's onboard buzzer. A duration can be specified in milliseconds, otherwise the wave continues until a call to Esplora.noTone().

Only one tone can be generated at a time. If a tone is already playing, the call will set its frequency.

Use of the tone() function will interfere with fading the red LED.

#### Syntax

Esplora.tone(frequency, duration)

#### Parameters

frequency: the frequency of the tone in hertz - unsigned int

duration: the duration of the tone in milliseconds (optional) - unsigned long

#### Returns

nothing
