As part of a project three students created a machine, based around an Arduino board, that will create a series of unusual sounds using unusual methods. Using the Arduino, many piezo elements, a toy xylophone, and much more - they have created a sound-effects machine that not only looks interesting but also works very well. You can see it in action below:
When developing your own Arduino-embedded projects, consider the Freetronics LeoStick:
Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. For more information and to order, click here.
