Priya Iyer- Quack!

Description:
In this assignment, I decided to go ahead with FSR. I first placed it inside the rubber duck and visualize the sound. But, once I put the FSR in, the gap was too wide for the sound. So, I decided to synthesize the sound made by the duck using the 'Minim' library (Google search win) for playing sounds. Thus, whenever the user applies pressure on the duck, it transmits the pressure onto the FSR which in turn provides for the input data to my code in Processing. My code then visualizes the pressure applied and also makes a 'quack' sound whenever the pressure applied is above certain units.
The code on the Arduino learning page for Processing helped a lot. Also, this code: http://code.compartmental.net/tools/minim/quickstart/ helped me a lot in getting started with sound outputs in Processing.
Components Used:
1 Arduino Uno Board
1 Bread Board
1 Force Sensitive Resistor
1 Rubber Duck
1 Sponge Base
1 10K Ohm resistor
Connecting Wires

TUI Assignment : FSR and Processing!

This code reads the pressure applied on the duck to make sounds and to visualizes the force applied on the Serial Monitor

Code inspired and modified from:

1. http://arduino.cc/en/Tutorial/Graph and

2. http://code.compartmental.net/tools/minim/quickstart/ (for sound)
