    4.  Spot how the LEDs on the micro:bit are arranged.

                                    (i)  4 rows and 4 columns                  (ii)  5 rows and 5 columns

                         5.  Identify why LEDs are important in the micro:bit.

                                    (i)  Store data                            (ii)  Add brightness

                                    (iii)  Show code output                    (iv)  Control movement

                      B.  Write ‘T’ for true and ‘F’ for false.

                         4.  Show string shows any number on display.

                         5.   The LEDs on the micro:bit are very important because they help us see what
                             our code is doing

                      C.  Fill in the blanks using the given hints:
                         1.  Each of the                   tiny lights can either be on (bright) or           Hints

                         3.  The micro:bit has two buttons labeled A and B on its                    .         LED
                                                                                                              Lights
                         4.  When you use the micro:bit, you can tell it which                      to
                             turn on or off.

                         5.  One of the coolest things about the micro:bit is its                     display.

                      COMPETENCY-BASED QUESTIONS

                      1.  Aarav created a project using a micro:bit where pressing Button A shows a happy face
                         and pressing Button B shows a sad face. What does this activity help him understand
                         about the micro:bit?

                      2.  When Riya used the show leds block in MakeCode to design a heart pattern on the
                         micro:bit, she noticed that the LEDs turned on and off to form shapes. What concept is
                         Riya exploring through this activity?
