10mm Continuous Buzzer PCB Mount This is the 10mm continuous buzzer PCB Mount , A buzzer is a small yet efficient component to add sound features to our project/system. It is a very small and compact 2-pin structure hence can be easily used on breadboard, Perf Board and even on PCBs which makes this a widely used component in most electronic applications. This a simple buzzer which when powered will make a Beep Beep Beep. Sound due to the internal oscillating circuit present inside it. But, this buzzer is most widely used because it can be customized with help of other circuits to fit easily in our application. If you want to use this buzzer in your Arduino project, then you will need few essential components like breadboard , jumper wires and resistors.

12 Volt Piezo Buzzer Plate (25mm) A 12 Volt Piezo Buzzer Plate (Small) is a device that uses the piezoelectric effect to measure pressure, acceleration, strain or force by converting them to an electrical charge These devices can be used both as sensors and actuators, so they're referred to as transducers, a term applied to any device that can convert one form of energy to another. The sensor turns mechanical energy into electric potential, and the actuator converts electrical energy into mechanical force or motion. The Piezoelectric material used here, ceramic lead zirconate titanate known as PZT has the ability to provide twice the voltage of Quartz under a given force. These transducers are simple, reliable, and very robust, and so find wide use in industry, medicine, and aero-space work. They're unaffected by external electromagnetic fields, and so can be used in applications where electronic sensors would fail. They are stable over a broad range of temperatures, but may be effected by long use at high temperatures. If you want to use this Piezo Buzzer Plate to make small piezo electric generator, for that you will need switch , wires and diodes.
