First, make sure that the correct Ameba development board is selected in "Tools" -> "Board"

Next, Connect the buzzer to the PWM output pin shown in the wiring diagram below:

The programming of the Ameba RTL8722DM can be done using Arduino IDE which makes it very easy to write code and upload code to the Ameba Board.

To open the example code in Arduino IDE, Open "File" -> "Examples" -> "AmebaHttp" -> "SimpleHttpExamples"

Verify and Upload the code on the Arduino IDE and press the reset button on Ameba.

Once the upload is complete. You can hear the buzzer playing music.
