Arduino Function: WiFiLinkClient

Description

This function creates an object client, that can connect to a specified internet IP address and port.

Syntax

WiFiClient()

Examples

/*
Web client

This sketch connects to a website (http://www.google.com)
using an Arduino board with WiFi Link.

This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.
