+  Simple WebSocket client for ArduinoHttpClient library
+  Connects to the WebSocket server, and sends a hello
+  message 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
