M2M Demo – Lesson #5 : Generating Sound with a Buzzer
In this sixth tutorial, we will learn how to use a piezo buzzer to generate sound. It will explain the principle of the reverse piezoelectric effect. You will use your Android device to select a note’s frequency value which will be transmitted to your ADK board to generate a sound with the piezo buzzer.
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.
