+ WiFiEsp example: ScanNetworks
+
+ This example  prints the Wifi shield's MAC address, and
+ scans for available Wifi networks using the Wifi shield.
+ Every ten seconds, it scans again. It doesn't actually
+ connect to any network, so no encryption scheme is specified.
+
+ For more details see: http://yaab-arduino.blogspot.com/p/wifiesp.html
