==== About the Arduino FFT Library ====


==== Programming Examples ====

Libraries: Arduino1.0 or Arduino-0022 (should work with both)

==== Installing Libraries ====

The above files need to be placed in the ''libraries'' folder inside of your Arduino sketch directory.  After you unzip !ArduinoFFT.zip, take the FFT folder and place it in your ''libraries'' folder, restart Arduino and load one of the example programs to test out the library.

If you are not certain where the ''libraries'' folder is located on your computer, try the following:

===== PC =====
Open up the Arduino software, and go to '''Sketch -> Add File...''', and a window will pop up that is your sketch folder.  This is usually ''C:\Documents and Settings\<your user name>\My Documents\Arduino''.  If you see a ''libraries'' folder, put the !AudioCodec library in there.  If you don't already have one, create the ''libraries'' folder in that directory.
