    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.
