[PD] questions about Firmata and [arduino]

[Adityo Pratomo]

Hi there everyone. Lately i've been working with an arduino board loaded
with the firmata firmware and then i use the [arduino] object to read the
input from the sensor that connected to the board's input port. For the
firmware, i choose to upload the simple_digital_firmata code from the
Library-Firmata example. And everything just went well. After some
examination, i made an assumption that this code is actually doing the
almost same thing done by the [arduino] object.

So my questions are is my my assumption true? if so, is the firmata code is
used by the arduino board so that it can communicate with the computer, and
the [arduino] object will maps those I/Os from the board to the pd? Actually
what does the [arduino] object does when it's started up for the first time?
The last question is Why can't i get the [arduino] board to respond when i
upload the standard_firmata code?

Thank you so much every body, sorry for the long questions, i'm so curious
here :)
