Creating audible alerts and simple tunes with an Arduino isn't difficult at all, and by using the Arduino tone() functions you can create some reasonable noises and tunes. To help use this method, Ryan Jackman has written a neat tutorial on not only the sketch functions, but also the basics of wiring a simple speaker to the Arduino safely which allows for a louder sound output than typical piezo buzzers. The results are quite good, such as the following classic example:
There isn't much to it, and you can be playing tunes with little effort - so visit Ryan's Instructable page to find out how. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
Have you been reading about Arduino and the types of projects created, but not sure where to start? Then order one our Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects!
