micro:bit 物聯網 課程 系列  -- 音樂播放

Another fantastic feature of the micro:bit is its ability to generate musical notes. This makes it very easy indeed for even quite young children to program simple songs.

Task:

Algorithm:

When button A is pressed.

Display the message Happy Birthday!

micro：bit的另一個奇妙功能是它能夠生成音符。 這使得即使是非常年幼的孩子也可以很簡單地編寫簡單的歌曲。

任務：

編程 micro:bit 播放“生日快樂”的前幾個小節。

算法：

Model:

There is no model for this task. A small piezo sounder that will operate at 3V must be connected between pin0 and GND.

You can use a speaker with a standard 3.5mm jack plug. See the diagram on the right for the connections when using pin0.

模型：

這個任務沒有模式。 必須在pin0和GND之間連接一個以3V工作的小型壓電式發聲器。

您可以使用標準3.5mm插孔的揚聲器。 使用pin0時，請參見右側的連接圖。
