-Rotary Dial
-===========
-
-Arduino library to read numbers from a rotary dial (or otherwise using pulse dialing; see [Wikipedia: Rotary dial](http://en.wikipedia.org/wiki/Rotary_dial)).
-
-![front of a rotary telephone dial](http://www.markfickett.com/umbrella/images/111105rotarydialfront-sm.jpg "Rotary Dial")
-
-This implementation is for the North American system, where [1, 9] pulses correspond to the numbers [1, 9], and 0 is represented by 10 pulses. This library was written for use with the dial [demonstrated here](http://commons.wikimedia.org/wiki/File:Rotary_Dial,_Dialing_Back_with_LEDs.ogv) and pictured above.
-
-Connection & Circuit
---------------------
-
-On the back of the dial are two connections relevant for this implementation.  One (the 'ready' switch) is normally open (NO), and is closed whenever the rotor is not at rest (specifically, as soon as the user draws back the rotor, and until it finishes returning). The other (the 'pulse' switch) is normally closed (NC), and is opened briefly for each pulse (roughly 10 - 20 Hz).
-
-The expected circuit is:
-
-	     Rotary Dial                              Arduino
-	                      /---------------------- readyPin
-	  /- ready switch (NO) -- pull-up resistor -- VCC
-	 /-- pulse switch (NC) -- pull-up resistor -/
-	 \                    \---------------------- pulsePin
-	  \------------------------------------------ GND
-
-The expected sequence is:
-
-	readyPin  pulsePin  state
-	HIGH      n/a       default (waiting)
-	LOW       LOW       ready to dial / for first pulse
-	LOW       HIGH      pulse received (number = 1)
-	LOW       LOW       ready for next pulse
-	LOW       HIGH      pulse received (number = 2)
-	LOW       ...       (repeat)
-	HIGH      n/a       rotation complete, count recorded
-
-There is 15ms allowed for debounce, which is the implementation's only
-constraint on pulse speed.

+
+This directory is intended for project header files.
+
+A header file is a file containing C declarations and macro definitions
+to be shared between several project source files. You request the use of a
+header file in your project source file (C, C++, etc) located in `src` folder
+by including it, with the C preprocessing directive `#include'.
+
+```src/main.c
+
+#include "header.h"
+
+int main (void)
+{
+ ...
+}
+```
+
+Including a header file produces the same results as copying the header file
+into each source file that needs it. Such copying would be time-consuming
+and error-prone. With a header file, the related declarations appear
+in only one place. If they need to be changed, they can be changed in one
+place, and programs that include the header file will automatically use the
+new version when next recompiled. The header file eliminates the labor of
+finding and changing all the copies as well as the risk that a failure to
+find one copy will result in inconsistencies within a program.
+
+In C, the usual convention is to give header files names that end with `.h'.
+It is most portable to use only letters, digits, dashes, and underscores in
+header file names, and at most one dot.
+
+Read more about using header files in official GCC documentation:

+* Include Syntax
+* Include Operation
+* Once-Only Headers
