Did you use processing to do the processing part?
That looks like the arduino IDE but isn’t.

what processing?
should i download it?

Yes, at processing.org
It has the grey interface you see in the video.
The blue interface is the arduino IDE to upload sketches to an arduino board.

and another question,
should i upload firmata into arduino
and the the whole touch OSC scetch?
