 /*
   LED bar graph
- 
+
   Turns on a series of LEDs based on the value of an analog sensor.
   This is a simple way to make a bar graph display. Though this graph
   uses 10 LEDs, you can use any number by changing the LED count
   and the pins in the array.
-  
+
   This method can be used to control any series of digital outputs that
   depends on an analog input.
- 
+
   The circuit:
    * LEDs from pins 2 through 11 to ground
