The best way to produce sound with an Arduino unit is probably by using the Sparkfun MP3 Player Shield, which is an extra circuit board for the Arduino which can play MP3 files from a microSD card. The costs, however, are $25, which is too much unless the TU happens to have one we can borrow, which we will find out as soon as possible. But it’s best to consider cheaper options.

The Arduino has one function that’s widely used to produce sounds, namely tone(). This function can be used to produce tones of a single frequency.

Multiple tones can be combined to form more complex noises, but playing a tune with chirping birds or something to wake someone up would probably be too difficult.

The best way to produce sound with an Arduino unit is probably by using the Sparkfun MP3 Player Shield, which is an extra circuit board for the Arduino which can play MP3 files from a microSD card (seen in the picture to the right). The costs, however, are $25, which is too much unless the TU happens to have one we can borrow, which we will find out as soon as possible. But it’s best to consider cheaper options.
