Ask AIRO
How can I make the micro:bit’s LEDs show a custom shape using the “show leds” block?
Why Are LEDs Important?
The LEDs on the micro:bit are very important
because they provide quick and clear visual SMART LEDs use less
feedback, making it easier to understand SPARK power compared to
what is happening in a program. This makes traditional bulbs.
it more fun and easier to understand how
coding works.
For example, if you wanted to show your name on the micro:bit, the LEDs would
light up in a pattern that looks like the letters of your name.
