 This is particularly useful for applications where hardware PWM modules are either unavailable or insufficient.
 
 ### Features
-Generates PWM signals with the following duty cycles: 5%, 25%, 50%, 75%, and 90%.
-Allows dynamic switching between duty cycles using an external button.
-Uses Timer0 for precise control over the PWM signal.
-Employs an external interrupt (INT0) to trigger duty cycle changes.
