The LED matrix on micro:bit can also function as light level sensor.

Let’s program ZOOM:BIT to automatically turn ON its headlights when the surrounding

is dark, and turn OFF when it is bright.

Do You Know?

Extensions are sets of
custom blocks that we
add to MakeCode Editor
to enable us to easily
program micro:bit
accessories, such as our
ZOOM:BIT robot.
