2. Emoji Display

They will discover how to select and display different emoji patterns on the
micro:bit’s LED screen, which uses small lights to form the images.

Observations

During the Displaying Emojis activity, students will notice:

When the program is executed, the micro:bit lights up and shows the emoji
on its LED screen.

They can modify their code to change the displayed emoji, such as switching
between a heart or a happy face.

Students will see how coding and computers can be used to create fun visuals

and designs.

Application

The ability to display emojis on the micro:bit can

be used to create interactive badges or wearable
devices that show different emotions or symbols.

Making a Counter Program

Variable: In programming, a variable is like a special storage box that holds

different types of information, such as numbers, words, or data. Imagine it as
a labelled container where you keep something you may need to use later. In
coding, variables can store values that may change while the program runs.

This program uses a variable called ‘count’

to keep track of the number you’re counting.

It sets the variable to 0 at the start.
Every time you press button B, it increases

the count variable by 1 and shows it on the
LED display.

Numbers over 9 won’t stay on the display, so

pressing button A shows the number.

You can reset the counter by pressing buttons A and B together.
