If you want to add beeps, tones or alerts to your Raspberry Pi project, you require a Piezo Buzzer! This buzzer requires no external oscillation, simply place a voltage of between 9V & 15V DC, across the terminals and it will make noise!

This one comes with two wires attached and two screw mounting points, so it can easilly be integrated onto a breadboard or into a circuit! To use you’ll need a voltage source such as a battery; simply connect the black wire to the negative of the voltage source and the red wire to the positive point that voltage source. This buzzer requires no external oscillation, simply place a voltage across the terminals and it will make noise!
