STEP 11: If our time is even (60, 58, 56...) we'll create a star. But first, we need a random y-coordinate!
Add another Random Integer indented in the if-statement. It should be indented twice ········¬
Change my_var to y and the range to (0, 230).
To make the stars appear randomly on the stage, we need a random xy-coordinate pair! Stars should appear anywhere horizontally, but only in the sky, so our random ranges for our x and y are a little different.

Micro:bit can only connect to one web page at a time.
Try stopping other Codesters projects or closing
other tabs or windows that may be using your Micro:bit.
If that doesn't fix the problem try disconnecting your Micro:bit,
