    Logic–Variables

                     Variable blocks are used to store values like counts, scores or distances and track changes in a
                     project. They help control the robot’s behaviour based on these values. You can create a new
                     variable with the Make a Variable button, which acts as a container for storing and updating
                     values like numbers or text.
                     Some of the important Variables blocks are as follows:

                                    Block                                          Description
                                                           This block  refers to  a custom  variable  that  you  create  in
                       myVariable
                                                           your project.

                       set  myVariable  to  1              This block assigns a value to the variable.

                                                           This block  increases  or decreases  (if you  use  a  negative
                        change  myVariable  by  1
                                                           number) the value of the variable by a specified amount.

                     Logic–Comments

                     Comment blocks are used to add notes or explanations within the code. These notes
                     are not executed by the program but help programmers understand the purpose of             comment
                     different parts of the code, making it easier to read and maintain.

                            Identify and explain the blocks given below:

                            1.     FrontEye   is near object?

                            2.   convert  0  to  text

                            3.      0   =      50

                     PROGRAMS USING DIFFERENT PLAYGROUNDS

                     In this section, you will create programs to help your robot move through different playgrounds.
                     Each playground  has a unique  layout  that  challenges you  to  plan and code  the robot’s
                     movement carefully.

                     Coral Reef Cleanup
                     In  the VEXcode  VR  simulation,  the  coral reef environment  teaches  about  the  importance  of
                     keeping oceans clean. The robot is programmed to collect trash from the seabed, showing how
                     technology can help protect marine ecosystems and promote environmental awareness.

                                                                                                                        91
