Play tones in headphones using Arduino


I would like to play audio tones in headphones using Arduino, and would appreciate some help about how to do this. The headphones should be able to play stereo tones in various frequencies based on a signal from the Arduino. I hope there is some breakout board from sparkfun or something similarly easy for this.



The Same tone in each headphone or different? How do you want the tone played?, when you press a button or other input?

Have you looked at the tone tutorial?
