/* ESP32 HTTP IoT Server Example for Wokwi.com

  https://wokwi.com/arduino/projects/320964045035274834

  To test, you need the Wokwi IoT Gateway, as explained here:

  https://docs.wokwi.com/guides/esp32-wifi#the-private-gateway

  Then start the simulation, and open http://localhost:9080
  in another browser tab.

  Note that the IoT Gateway requires a Wokwi Club subscription.
