/*
	Esp8266 Websockets Client

	This sketch:
        1. Connects to a WiFi network
        2. Connects to a Websockets server
        3. Sends the websockets server a message ("Hello Server")
        4. Prints all incoming messages while the connection is open

	Hardware:
        For this sketch you only need an ESP8266 board.
