/* ESP32 HTTP Client example

  https://wokwi.com/projects/384757860096897025

  This project makes an HTTP GET request to https://www.google.com/search?q=arduino every 5 seconds.

  If you want to request from a local server you can uncomment and configure getLocal() but you need the Wokwi IoT Gateway, as explained here:

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

  Note that the IoT Gateway requires a Wokwi Club subscription.
