/*
Arduino Yun Wireless Config Check
Checks the wireless state of Arduino Yun by calling
the linux command iwconfig.
Upload this to an Arduino Yun via serial (not WiFi)
then open the serial monitor to see the status of
your Yun's WiFi connection. If it's connected to
a wireless network, the ESSID (name) of that network
and the signal strength will appear.
The circuit:
* Arduino Yun
