Tell us about yourself!
Hello, I think this tutorial is wonderful, thank you so much for posting it, however I've run into a problem now. When I hook the Arduino up to an oscilloscope, it shows a perfect sine wave. However, when I plug my Arduino into my audio interface, so I can record the output on my computer, the signal becomes truncated and only has a peak to peak voltage of 80 mV. Could you please help me understand why this is happening, and what I can do to fix it?Thank you.
