you can use analogWrite instead of digitalWrite when calling from API.
You can refer to this.

Use analogWrite(‘pin_number’,‘intensity_value’)
The intensity value can be between 0-255 which makes the pin act as a PWM source.

you can change the sound of buzzer by using anlaogWrite at the place of digital write ,
for eg.
onclick=“analogWrite(0, ‘255’);”
(YOU CAN VARY THE VALUE OF 255 TO GET DIFFRENT SOUND )
(0,‘255’)-HERE FIRST VALUE THAT IS 0 IS DIGITAL PIN NO. IT CAN BE 1,2,3,4
