Passive Buzzer 5v Pay attention, this is a buzzer, not an active one, so if you connect a voltage of five volts to it, it will not make a sound, and in order for it to make a sound, a frequency must be issued to it, and not a constant voltage It works like a mini stethoscope If you want to connect 5 volts, it will make a sound, you must use Active Buzzer from this link نعتذر الشراء من الموقع متوقف مؤقتا We apologize : purchasing from our website is temporarily stopped
