    that show order numbers. These displays help
                      customers know when their food is ready. When

                      an order is placed, the restaurant staff updates
                      the number on the display. Once the order is

                      prepared,  the  number  flashes  on  the  screen,
                      notifying the customer. This application makes
                      the process efficient, ensuring customers are

                      served in the correct order without confusion.

                      How Sound Sensors Work?

                      The  micro:bit  with  sound  has  a  built-in
                      microphone sensor. It can react to loud and

                      quiet  sounds,  and  also  measure  how  loud
                      your environment is.

                      It  can  be used  to  respond  to  sound. The

                      microphone  input  sensor  is located  on  the
                      front  of  the  board  alongside  a  microphone
                      activity LED, which is lit when the microphone is in use.

                         • When the microphone detects a loud sound, like a clap, it shows a large

                         heart on the LED display.
                         • If it detects a quiet sound, for example after your clap has finished, it shows

                         a small heart.
                         • The effect of this is to create a simple heart animation

                         that responds to claps or strong beats in music.
                                                                                                    START
