Instructions: 1. Begin by setting up the foundational structure of the GUI application. This will include initializing the main window and setting its properties. 2. Design labels for "Color", "Duty Cycle", "TON", and "TOFF". Position them appropriately. 3. Incorporate checkboxes to allow the user to select which LED colors (Red, Green, Blue) they wish to control. 4. For each LED color, provide entry fields for the user to input values for the duty cycle, TON, and TOFF. 5. Include operational buttons: An "OK" button to display the selected LED colors and their properties. A "Clear" button to reset all input fields. An "Upload to Arduino" button to simulate sending the chosen configurations to an Arduino. A "Quit" button to close the application. 6. Create event handlers for each button to define their functionalities. 7. Ensure the GUI layout is organized and user-friendly. Hints: Utilize Label, Entry, Button, and Checkbutton from the Tkinter library. Consider the grid method for positioning GUI elements. Use IntVar() for checkbox states. Event handlers (or callback functions) are essential for interactive GUI applications. Create these functions to handle actions for each button.
