/* NOTE ABOUT ARDUINO PINS
 * Pins 13, 12, 11 are always used by the SD card (they are the only pins that have a high speed SPI interface). 
 * Then there are 5 other pins used to talk to the DAC and SD card, but they can be set to connect to any arduino pin. 
 * However, by default, the library is configured to use pins 10 (for SD card) and pins 2, 3, 4 and 5 for the DAC. 
 * To chanage these pins requires modifying the library - the pins are referenced by their 'hardware' pin names (ie PORTD, etc) not by arduino pins. 
 * That means pins 6, 7, 8, 9 and the 6 analog in pins (also known as digital i/o pins 14-20) are available.
