/**
 This example sketch compiles for Pi PicoW, Pi Pico2W
 The project has been tested using Arduino IDE V2.3.8, Pi Pico board support V5.5.1

 This sketch does NOT serve pfodWeb from the micro file system
 see pi_picoCharting_Server.ino for a sketch that serves pfodWeb directly from the micro
 
 Setup Notes:
 Before running this code.
  a) Set the ssid and password (see WiFi Settings in the code below) to match your local network's router, ssid and password
  b) Set a static IP to an unused IP on your network OR leave as blank and check the Serial monitor for the assigned IP
  c) Upload the sketch, Open the IDE Serial Monitor to see what IP has been assigned
  d) From the pfodParse library, in sub-directory pfodWeb, open pfodWeb.html in a Chrome or Edge browser (>V141)
     and selected HTTP connection, fill in the IP for this board, click Connect to display the On/off buttons
