An Arduino based RS232 controller for two Waveplayer8.

For the code I needed a little bit of reverse engineering. A CRC control byte is send, too. The polynom that is used is: 0xD5. The code for that was in the manual

The controller plays random files and pauses depending on the value of a potentiometer.

One can change the length of the pause (in seconds):

 unsigned long longest_pause = 100;

The track number:

 int number_of_tracks = 8;  // number of all tracks

And in an array one can write the individual length of each track (in seconds):

 unsigned long length_of_tracks[] = {11, 12, 13, 14, 15, 16, 17, 18};
