MaxMSP patch: arduivis_model6_multipleFeedbacks.maxpat

This is an example of to read sliders from MaxMSP. 
An Arduino reads and parses this data, sending
it from the Arduino and back into MaxmSP. This 
feedback data is then sent back to the Arduino
from MaxMSP, controlling the PWM of a LED. 
This is done with several streams of data in 
this example.
