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
