 /*
   Serial Call and Response
  Language: Wiring/Arduino
- 
+
  This program sends an ASCII A (byte of value 65) on startup
  and repeats that until it gets some data in.
- Then it waits for a byte in the serial port, and 
+ Then it waits for a byte in the serial port, and
  sends three sensor values whenever it gets a byte in.
- 
+
  Thanks to Greg Shakar and Scott Fitzgerald for the improvements

    The circuit:
- * potentiometers attached to analog inputs 0 and 1 
+ * potentiometers attached to analog inputs 0 and 1
  * pushbutton attached to digital I/O 2
