The Paint Bucket Tool is a physical computing project in which I use an Arduino microcontroller and a 3-axis accelerometer to build a drawing tool.

The idea is to control an application build in processing changing the rate of the sound and the position, scale, and color of forms with the manipulation of a physical bucket. The programming map a spiral to the changes of velocity in the Y axis of the Paint Bucket Object and place circles which position, color and scale are determined by the change of the velocity in the 3 axis.  The change in the speed of movement in the Y-axis also controls the rate of the sound.

At first I was using the MMA 7260Q accelerometer but I couldn't get consistent numbers. One of the problems trying to use the circuit as a "shake" sensor was to be able to have "stable" connections and data. The MMA 7260 works only in very controlled situations. (Loose wires can create false signals )

Finally I end up working with a ADXL3xx acceloremeter.
