                     In this project, the icon will blink on the screen, repeating a cycle of showing and
                     hiding. First, the selected icon, such as a heart or a grid, will appear for 1 second.
                     After that, the screen will remain empty for 0.5 seconds before the icon appears
                     again. This pattern will continue over and over, making the icon blink on and off.
                     The program uses a Forever loop to keep repeating this process, so the icon keeps

                     blinking as long as the program is running.
