sound input with flexinol and led output
we rebuilt the puredata file to also include an led responding to sound with pwm, as well as an option for adjusting the input's amplitude threshold.

audio input and pwm led output
using our mic-in program along with a couple decibel converters, we wrote a program using audio as input through the laptop microphone to control the pulse width modulation of an led (dimming). the led's intensity varies according to the amplitude of the sound input. we also have the audio signal writing to an array/wave.

led pulse width modulation with pure data
with an arduino, a breadboard, and pure data, we modified our led toggle program to use a pulse width modulator (pwm) to simulate an analog output in order to dim an led.
