   library. This example sends a GET and a POST request with a custom header every 5 seconds.
 
-  note: WiFi SSID and password are stored in config.h file.
-  If it is not present, add a new tab, call it "config.h"
-  and add the following variables:
-  char ssid[] = "ssid";     //  your network SSID (name)
-  char pass[] = "password"; // your network password
