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 1.5V & 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 easily 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.
