From bottom clockwise: Physical data board, the flex sensor, board application, laptop application and visual display.
Demonstration of visualizing physical computing. A bending sensitive sensor (Piezo) connects to an Arduino Uno input pin. The Arduino Sketch outputs the measured values of bending. The Processing Sketch reads the stream of inputs and changes the location of the dots. The visualization is one that came with the sample code. Its meaning is in demonstrating capacity of these tools for interesting work. I wonder whether the Scratch or html5 crews are up to creating more meaningful charts of displacement v. time.
