| WiFi Status | |
| This sketch runs a script called "pretty-wifi-info.lua" | |
| installed on your Yún in folder /usr/bin. | |
| It prints information about the status of your wifi connection. | |
| It uses Serial to print, so you need to connect your YunShield/Yún to your | |
| computer using a USB cable and select the appropriate port from | |
| the Port menu | |
