Program a micro:bit: Hello, World!

The traditional way to start programming in a new language is to get your computer to say, “Hello, World!”.

Connect the mico:bit to the computer with the USB cable.

Drag and drop the file in the MICROBIT device.

Program’s explanation

The first line:

# Add your Python code here. E.g.

… is a comment. The MicroPython language doesn’t care to it. A comment begins always by #.

The second line:

from microbit import *

…tells MicroPython to get all the stuff it needs to work with the micro:bit. All this stuff is in a module called microbit.

The third line:

while True:

… is a infinite loop. The loop works while True is true! The indent code is in the loop.

The fourth line:

display.scroll('Hello, World!')

…tells MicroPython to use the display to scroll the string of characters “Hello, World!”.

The fifth line:

display.show(Image.HEART)

… tells MicroPython to use the display to show the HEART image.

The sixth line:

sleep(2000)

… tells MicroPython must wait 2 000 milliseconds.
