more detailed example for web server

[saraheno]

Hi,
Thank you for making this very nice library. I enjoyed using the example webserver at https://docs.arduino.cc/tutorials/uno-wifi-rev2/uno-wifi-r2-hosting-a-webserver

That examples shows how to implement simple buttons. It would be very useful, though, if there were an input form that could say accept an integer that could be used to set the duty cycle on the PWM pins. Is that possible? Or say an input field for a delay?

Are there any examples showing this?
