Please have a look at my YouTube video first.

You see, I can type musical note and play it by web.

D-duino is such things. You can check your input content on its OLED display.

And you can do a lot of interesting things by WiFi.

Not so many things

D-duino-B x1

Grove shield for D-duino x1

18650 Battery shield x1

Grove speaker x1

I put all code on github

You should look at grove speaker wiki first

Here I connected speaker to D3. But Arduino code D3's pin number is 0.

You can type 12 musical notes by changing code.

I hope the code example can help you a lot!
