Arudindiana Jones

Here goes the indiana jones theme:

And the code, for which I had to figure out a few new notes (I did so using my midi keyboard and garage band and just “hand tuning” the arduino code.

/*Based on Melody
* (cleft) 2005 D. Cuartielles for K3
*
* This example uses a piezo speaker to play melodies.  It sends
* a square wave of the appropriate frequency to the piezo, generating
* the corresponding tone.
*
* The calculation of the tones is made following the mathematical
* operation:
*
*       timeHigh = period / 2 = 1 / (2 * toneFrequency)
*
* where the different tones are described as in the table:
*
* note frequency period timeHigh
* c         261 Hz         3830 1915
* d         294 Hz         3400 1700
* e         329 Hz         3038 1519
* f         349 Hz         2864 1432
* g         392 Hz         2550 1275
* a         440 Hz         2272 1136
* b         493 Hz         2028	1014
* C	        523 Hz	        1912 956
