                              BLOCKS EDITOR AND ITS INTERFACE

                      In MIT App  Inventor, the  Blocks  Editor is  where you  design  your  app’s  actions.
                      You can drag and drop blocks to make things happen, like showing a message
                      or changing the screen, much like assembling a puzzle. The Blocks Editor lets you

                      program the app’s behaviour by putting blocks together.

                                                                                                                  Blocks
                                                                                                                  Button

                                                                                Blocks

                       Component-Specific
                                    Drawers
                                                                                                                  Viewer

                      The important sections of the blocks editor window:

                           Built-in Blocks: These are the basic blocks in MIT App Inventor (e.g., Control,

                          Math, Text) used to program app behaviour.
                           Component-Specific Drawers: Each component (e.g., Button, Label) has its own set

                          of blocks for controlling actions and settings.
                           Blocks Button: Switches you from the design area to the blocks area to write the

                          app’s code.
                           Viewer: The viewer is where you drag and drop blocks to create your app’s
                          functionality by connecting them like puzzle pieces.
