/* Play Melody<br />
* -----------<br />
*<br />
* Program to play a simple melody<br />
*<br />
* Tones are created by quickly pulsing a speaker on and off <br />
* using PWM, to create signature frequencies.<br />
*<br />
* Each note has a frequency, created by varying the period of <br />
* vibration, measured in microseconds. We'll use pulse-width<br />
* modulation (PWM) to create that vibration.<br />
<br />
* We calculate the pulse-width to be half the period; we pulse <br />
* the speaker HIGH for 'pulse-width' microseconds, then LOW <br />
* for 'pulse-width' microseconds.<br />
* This pulsing creates a vibration of the desired frequency.<br />
*<br />
* (cleft) 2005 D. Cuartielles for K3<br />
* Refactoring and comments 2006 clay.shirky@nyu.edu<br />
* See NOTES in comments at end for possible improvements<br />

/*<br />
* NOTES<br />
* The program purports to hold a tone for 'duration' microseconds.<br />
* Lies lies lies! It holds for at least 'duration' microseconds, _plus_<br />
* any overhead created by incremeting elapsed_time (could be in excess of <br />
* 3K microseconds) _plus_ overhead of looping and two digitalWrites()<br />
* <br />
* As a result, a tone of 'duration' plays much more slowly than a rest<br />
* of 'duration.' rest_count creates a loop variable to bring 'rest' beats <br />
* in line with 'tone' beats of the same length. <br />
* <br />
* rest_count will be affected by chip architecture and speed, as well as <br />
* overhead from any program mods. Past behavior is no guarantee of future <br />
* performance. Your mileage may vary. Light fuse and get away.<br />
* <br />
* This could use a number of enhancements:<br />
* ADD code to let the programmer specify how many times the melody should<br />
* loop before stopping<br />
* ADD another octave<br />
* MOVE tempo, pause, and rest_count to #define statements<br />
* RE-WRITE to include volume, using analogWrite, as with the second program at<br />
* http://www.arduino.cc/en/Tutorial/PlayMelody<br />
* ADD code to make the tempo settable by pot or other input device<br />
* ADD code to take tempo or volume settable by serial communication <br />
* (Requires 0005 or higher.)<br />
* ADD code to create a tone offset (higer or lower) through pot etc<br />
* REPLACE random melody with opening bars to 'Smoke on the Water'<br />
