+[TERMINAL WIDGET ESP32 EXAMPLE] =====================================================================================
+
+Environment prepare:
+In your Blynk App project:
+  - add "Terminal" widget,
+  - bind it to Virtual Pin V2,
+  - add input line option in widget settings
+  - Run the App (green triangle in the upper right corner).
+  - define your auth token for current example
+  - define SSID and WiFi password that will be used by ESP32 board
+  - run current example
+
+
+This started program will call and execute event handler "write_virtual_pin_handler" if new
+event comes from terminal app widget.
+In App Terminal widget you can type commands.
+'help' - info about available commnds
+'logo' - prints blynk library ascii logo
+'version' - prints blynk library version
+'sysinfo' - prints board system info
+'ls' - list target board dir. Example: 'ls /lib'.
+       root dir will be listed if no arguments provided
+
+For any other terminal inputs will be printed error info that provided command is not supported.
