Singing Arduino!

David Fowler was kind enough to write to us about the new uChobby article:

"This is the second in a series of articles about generating sound with an Arduino. The first article covered the various methods available for sound generation with an Arduino. In this article we take a small step; 'Hello World' for Arduino sound. We prepare for our future experiments by hooking up a PC or powered speaker so we can hear the Arduino sing."
