- Wifi Signal Strength Indicator
- 
- This example demonstrates the use of the bridge and process libraries 
- to communicate between the Arduino side and the linux side of the Arduino Yun. 
- 
- The Linux script returns the strength of the wifi signal.
- 
- The Arduino sketch uses LEDs to indicate whether the current value of 
- the signal strength is above, below, or the same as the last value 
- 
- The circuit: 
- * LEDs on pins 8, 9, and 10
- * Built-in LED on pin 13
- 
- The script:
- The following one line script must exist in the /root directory of the 
- linux file system, in a file named "wifiStrength.sh", and it must be executable:
- 
- tail -1 /proc/net/wireless | cut  -c22-23
