A piezo element to produce sounds
The piezo electric buzzer are used to produce sounds, beeps and alerts. This modele is bigger and louder than our piezo for breadboard. There are thin wires attached, we plugged them into a solderless breadboard but they might too thin to plug in directly into the Arduino socket headers. Anyway, just solder a 2 pins PinHeader on the wire and you will be able to use it more easily with Arduino and breadboards.
Piezo elements converts voltage to vibration (and produce sound) -or- vibration to voltage (knok it and it produce a voltage output).
So the buzzer can be used to produce beeps, tones and alerts AND can also be used to detect knock (fast movements), or use it under a drum pad or crash sensor.
This piezo element has a diameter of 30mm and enclosed inside an enclosure and mounting holes (to attach it easily).
It is designed to with with 12Vpp voltage but produce pretty lound sounds with 5V or 3.3V square waves. You can also For music use with an Arduino, check out the Tone tutorial.
