    Concepts

                     1.  Sound Detection

                         Students  will  learn  how  the  micro:bit  can  hear  sounds,  like  a  clap,  and
                        understand that it can be used to create fun programs.

                     2.  Programming Actions

                         Students will see how coding allows the micro:bit to do things based on what
                        it hears, like showing a heart when it detects a clap.

                     Observations

                     In the Clap Heart activity, students will notice:

                        When  they  clap, the  micro:bit  will  light  up  and  show  a  heart  on  its  LED

                        screen.

                        If they clap again, the heart will appear once more, showing that the micro:bit
                        is responding to the sound.

                        Students will enjoy seeing how sound can control the micro:bit and create a
                        fun visual.

                     Application

                     Sound sensor is in automatic lights that turn

                     on  when  you  clap  your  hands.  The  sound
                     sensor  listens  for  a  loud  sound,  like  a  clap,

                     and when it detects it, the lights automatically
                     turn on. This makes it easy to control lights
                     without needing to touch a switch.

                     Understanding Light Intensity Programs

                     A light sensor is an input device that detects
                     changes in light levels and can be programmed
                     to  use  this information  to  trigger  specific

                     actions in computer systems. For instance, you
                     can program the micro:bit to light up brightly
                     when it detects high light levels or dim when

                     it’s dark. The micro:bit uses its LED display as
                     the light sensor, allowing it to both emit light

                                                                        Introduction to Micro:bit and Programming  73
