Arduino Toolkit - @arduino/playTone

: playTone (ar, pin, freq, duration)

Play a tone of a given frequency on a specified pin.

Inputs

ar - connected arduino object

pin - digital pin to play tone on

freq - frequency in hertz to play between 0 and 32767Hz.

duration duration in seconds to play tone between 0 and 30 seconds

If duration is 0 or not specified, tone will continue to play until next tone is commanded. If frequency is 0, tone will stop playing
