Using a buffer to write sensor values to a SD card at 2000samples/sec+.
The time interval is 250um = 4000 samples/sec.
This works but produces alot of noise. Reading the Mic directly from A0.
Using SD Shield and SD FAT beta library (though the other one works) but code says must be newest version.
Define SD SS pin = 8 in the fastLogger sketch. Define the pins the SD library is ridiculous.
Works with the JAVA wav creator and reads hex as its faster.
