This project is an Arduino based step sequencer, synthesizer and sound effects box.
The user interface is kept very simple, with just four knobs, three push buttons, 8 LEDs and a power switch. The speaker is connected straight to a pin on the Arduino via the volume knob - everything is done in the Arduino using PWM to generate analog waveforms. The LEDs indicate the current step in sequencing mode, and provide light patterns in noise modes.
The basic features are:
- 16-step programable sequencer with adjustable frequency and duration for each step
- synthesizer with 4 output waveforms (sine, square, triangle and sawtooth)
- noise generation (sirens, laser beam, random noise)
- special random sound modes

The original intent of this project was to make a MIDI device that would scan in low resolution images on paper and play them as music. Turns out that even though it is only using a handful of LDRs (photo resistors) is makes for a pretty good image scanner also.
It uses LDRs to measure the gray-scale of specific point of a image, and triggers midi notes from a selected threshold. When the threshold is reached the velocity will be set by the darkness at that point. the darker point the higher the velocity will be.

Paola sent me a cool scarecrow project based on Arduino. But more details on the website please . Paola writes:
The goal is create a musical urban Scarecrow for rooftop gardens to avoid pigeons. As the cost of foods keep rising, more and more people are setting up little gardens to grow their own tomatoes, strawberries and herbs.

Boobie the Tweet Bird is a project for Multimedia in Artistic Environments.
we have a rude processing application reading the rss feed coming from Twitter, and everytime a new message arrives from the ones you’re following, the app sends a signal to Arduino, and the bird sings

Great construction, this Theremin using LC oscillator circuit generate the frequency signal like a capacitive sensor then feed to the Arduino board for generating sound using software. The position of the player’s hands controlling the frequency signal(sound).[link]
