   1_Inkplate_WiFi_HTTP example for e-radionica.com Inkplate 6
   For this example you will need USB cable, Inkplate 6 and stable WiFi Internet connection
   Select "Inkplate 6(ESP32)" from Tools -> Board menu.
   Don't have "Inkplate 6(ESP32)" option? Follow our tutorial and add it: 
   https://e-radionica.com/en/blog/add-inkplate-6-to-arduino-ide/

   This example will show you how to connect to WiFi network, get data from Internet and display that data on epaper.
   This example is NOT on to how to parse HTML data from Internet - it will just print HTML on the screen. 

   In quotation marks you will need write your WiFi SSID and WiFi password in order to connect to your WiFi network.
