Buzzer Related Doubt

The voice of my buzzer is very low. Is there a way I can increase the volume of the buzzer ?

Hello @sknabar13,
You can use the analogWrite function whose syntax is analogWrite(pin, value) and pass the value parameter as 255. This will increase the sound of your buzzer to the maximum level. Thank you.

Hi @sknabar13 ,
Try testing the buzzer by directly connecting it between 3.3V and GND.
