And now for something completely different - the "Snarky Swami" by Instructables member paulindallas. This is a clever Arduino-powered take on the mythical fortune-teller ... by waving your hand over the crystal ball, your fortune or other random advice will be dictated by the Swami.
However in reality this project is an Arduino-compatible board that can play simple audio files stored on an SD card. With the aid of a light sensor, the Arduino can detect when your hand is over the ball above the sensor and randomly play one of the pre-recorded audio files. A demonstration of this is shown in the following video:
Even if you're not interested in a fortune-teller, this project is a good example of audio file playback without extensive external hardware.

Looking for a small Arduino-compatible board to embed into final projects? Consider our LeoStick - it's the Arduino Leonardo-compatible board that's cheaper and smaller than the original:
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. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.
