Installation Descriptions

Short blurb:
Sarasong is an interactive art installation in which users place colored post its on a wooden board, which are then scanned by a self-moving webcam, analyzed, and converted into a musical composition.

Long blurb:
SaraSong is an interactive art installation involving a 4 foot by 6 foot wooden board. Users interact with it by placing post it notes of different colors onto the wooden surface. Every so often, the webcam mounted to the board passes across the surface of the board, scanning the post it notes that the users have placed. As the webcam passes across the board, the installation generates music based off of the colors that it "sees". The generated music chooses from multiple different instrumentations, allowing each interaction to be a completely different experience. The users also have the option of driving the webcam manually using a joystick, choosing which data they would like the board to convert into music. Occasionally, after the scan of the board is complete, a scraper mechanism is passed across the board, pulling some of the post its off the board, cleaning the board a little. The interpretation of the post its is done entirely autonomously, making the installation appear to be a living being.

Ok here is the updated diagram of the wiring set-up for our board. I made some changes to it the last one that was posted has some minor errors.

Board Wiring Diagram

So here is a wiring diagram for how our board is set-up. It utilizes the stepper-bee+ board.
Attached to the stepper bee are 2 stepper motors. The power supply is an old computer power supply we're using the 12v output for powering the stepper motors. The sweeper bot clears the post-it notes off of the board and the LED light flashes as a warning to people that the sweeper bot is active
