So, you want to make some sounds with the Arduino you just bought last Friday? Check out uCHobby as they show you how to do some basic stuff with sound and Arduino including how to make “Hello World” sound using a PC speaker.
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.
