don’t worry

Here’s the working hardware prototype. Unit on the left is the receiver (Xbee on Sparkfun Xbee breakout board + de-chipped Arduino) and the right one is the one of transmitters(Xbee on Xbee Lilypad breakout board). Receiver must be physically connected to the computer for data bridge. Receivers will work wirelessly on battery.

During my research, I found out that Xbee can operate standalone, transmit or receive data through 6 I/O pins. So I don’t have to use any microcontroller. Thanks to Dan Shiffman and Rob Faludi for Xbee Processing API, I managed to gather accelerometer data correctly (but needs noise filtering) and send to Ableton Live as MIDI signal. Next move is fine tuning.

“parametric” is my interactive multimedia senior project that includes audience into the audio/visual production process and gives them a chance to be a part of the performance.

Users will choose one of the controller and will manipulate audio and visuals in real time.

Every controller will have an accelerometer to produce data and a wireless transmitter to send it the computer for processing. Each controller will control specific parameter.

Software
Ableton Live and Processing to control parameters
Quartz Composer and VDMX to generate visuals

Hardware
Arduino Lilypad
Xbee
