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
