../../../_images/Chapter01_05.png

In this drop-down list of this code block, there are dozens of melodies to choose. You can choose any one.

Then download the code to micro:bit, and Rover will play melody of the code.

1.4. Play custom melody

Load code according to the table below or drag the code block as shown in the picture below:

../Projects/01.3_Custom-Melody

microbit-Custom-Melody.hex
../../../_images/Chapter01_06.png

In this code, an array is used to define a melody. Each data represents a note and a beat. For example, “C4:4” means that the note is C4 and the beat is 4. “G4:8” means that the note is G4 and the beat is 8. So you can create your own music.

Download the code to micro:bit, and Rover will play melody of the code.
