25w12 A New Learning Package Having Fun with Buzzer with Arduino

We have started a new learning package LP2512: Basic Array and Looping in C++, 25w12, the basic idea is to use the buzzer connected to Arduino UNO board, and we will follow step-by-step tasks designed in PJ021: Make Music Box with the Buzzer and Arduino, starting from understanding what is buzzer and how to generate sound using vibration, then eventually we will create a melody as a music box at the end of this learning package.

The designed knowledge point is array and for-looping in C++, this is already a little advanced topic in the coding, it's very necessary to build such useful competence, so we can take more interesting projects in the future, we even have already got an idea of what as the next project, we are very eager to bring our students to play more fun programming and robotics projects. So now, let's take some basic learning seriously.
