+  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:
