Sound Block

            Sound blocks are in pink colour. They control sound functions. We can add music to our

            Scratch project by using Sound blocks. You can even record your voice and save it. You can
            play it with a sprite.

                            block plays  a  sound  without  pausing  the  script.
              The sound options are “Meow” or recorded sound.
                                 block plays the sound by pausing the script

              until  the  sound  has  finished  playing.  The  sound  options  are
              “Meow” or any recorded sounds.
               To stop all sounds being played on all Sprites, use              block.

                          block clears all existing sound effects.
            Events Block

            An event is a happening which occurs due to some other things

            that happened before it. So, Events block actually control how
            the blocks in a script will start to run, if a particular action is
            done. Events blocks control events and the starting of scripts.
            They are yellow in colour.

                        block activates the script when the green flag or Go
              button is clicked.

                            block activates the script when the chosen key is pressed. You can choose
              from the given keys or you can choose the option any.

                         block activates the script when you click the sprite.


            Control Block

            They have looping blocks which are used when the same blocks have to be repeated for a
            number of times. The most commonly used control blocks are:

                           block pauses the running of the script for the number of seconds given in the
              block. You can use this block when two move or speak blocks are coming one after the
              other.

                The repeat block repeats a set of blocks for a given number of times. This
              block is also used to draw shapes where we have to give the same blocks
              again and again for a number of times.
                                    The forever block keeps on repeating a set of blocks till the stop button
                                  is clicked. This block is similar to repeat block and expands automatically

                                  to accommodate the blocks you snap inside it.
