    «   A  sensor is  a special  electronic  part  that  can detect  changes  such
                          as movement, light, sound, direction or temperature.

                       «   Sensors can detect movement, direction, temperature, light and more.
                       «   The Micro:bit also has built-in sensors that allow it to do similar things.

                       «   The Micro:bit  can sense movement  through its motion  sensor, also known as the
                          accelerometer.

                       «   The accelerometer measures movement in three directions: side to side, up and down,
                          and forwards and backwards.

                       «   The Micro:bit can show a visual indicator like an arrow pointing to the current direction.

                       «   The compass sensor is a great way to explore how real-world navigation systems work.

                                                                 Exercise

                     A.  Tick ( ) the correct option.

                        1.  Identify  the  sensor which helps to  detect  the  direction  in which the  Micro:bit
                            is facing.

                                   (i)  Temperature Sensor                   (ii)  Motion Sensor

                                   (iii)  Compass Sensor                     (iv)  Light Sensor

                        2.  What does the accelerometer detect in the Micro:bit?

                                   (i)  Temperature                          (ii)  Sound

                                   (iii)  Direction                          (iv)  Motion

                        3.  Mark the direction that compass sensor consider as 0°.

                                   (i)  North                                (ii)  South

                                   (iii)  East                               (iv)  West
