The ESP32 User LED

Just simulates switching on and off the ESP32 user LED

There is no connection to the ESP32 hardware and you can run this HTML file directly in your browser. No need to run a WEB server on the ESP32.
Of course you can also have this html file served by ajaxLEDServer.py on the ESP32. If you want to actually control the user LED on the ESP32 CPU you must start ajaxLEDServer.py with the page: serverIP/ledControl
picoweb requires the icon files to be stored on a directory /static
