    CREATING AN APP USING SENSORS

                     Sensors can create apps that respond to movement, like a Pedometer app, which counts steps
                     using a pedometer sensor and displays the count on the screen.

                     DESIGNING THE USER INTERFACE (UI) FOR THE PEDOMETER APP
                     To design the user interface for the Pedometer app, follow the given steps:

                     Step   1    Create new project in the MIT App Inventor.

                     Step   2     Change the name of the screen to  Pedometer in the  Title text  box, adjust
                                 AlignHorizontal to Center:3 and AlignVertical to Center:2 in the Properties pane.

                     Step  3     Click on the User Interface component.

                                                                                    MIT App Inventor has over 400,000
                                                                                    unique monthly active users.

                     Step   4    Drag and drop a Button onto the phone screen.

                     Step  5      Click  Button1 and  set  its  properties:  Text =  Start,  BackgroundColor  =  Green,
                                 FontSize ≥ 22, Shape = Rounded, TextColor = Black.

                                   Similarly, add Button2 with Text as Stop and Button3 with Text as Reset setting their
                                 BackgroundColor, FontSize, TextColor and Shape as needed.

                                                                                                                      75
