Block-based programming helps students quickly see the results of their
code, making it a fun way to learn programming and bring the micro:bit to life.

Simple Programming-Displaying Emojis

In this project, different types of icons will be

displayed on the micro:bit’s 5 x 5 LED matrix.
The display contains a total of 25 LEDs
arranged in a grid, allowing for various icons

to be shown. Some preset icons are available
in the block code, and users can also create
their own custom designs.

The micro:bit’s LED screen consists of 25 red

LEDs arranged in a 5 by 5 grid. You can control
individual LEDs by specifying their position using (x, y) coordinates, where x
represents the horizontal position (0–4) and y represents the vertical position

(0–4).

LED Grid Example:

Here are the x, y coordinates for the LEDs in
the 5 x 5 grid:

(0,0) (1,0) (2,0) (3,0) (4,0)

(0,1) (1,1) (2,1) (3,1) (4,1)
(0,2) (1,2) (2,2) (3,2) (4,2)
