M2M Demo – Lesson #6 : Sensing sound with a Buzzer

In this seventh tutorial, we will learn the principle of the piezoelectric effect. You will use the piezo buzzer to build a knock sensor that produces an electrical charge when the piezo element is oscillating. You will write an Android application in which the background changes each time a knock has been sensed. A simple ProgressBar UI element will visualize the current ADC value that has been sensed.

You will find :

– Arduino sketch

– Android code

– Documentation including : List of electronic components, Circuit diagram , Arduino sketch, Android main class script, and a photo of the result.

You can enhance the code or create new one 🙂

As usual all code is documented.

Best regards,
