linear CCD TCD1201d readout and timing issue

Hey guys, i'm in a project with this sensor. So, I saw the lesto's project, but i don't know how it doesn't work with me. I've try everything already. But it just doesn't work.

Some questions:
In this prototype, Do I need some resistor, capacitor or something else? or Can I put all directly on arduino?.

In this project: TCD1201D Arduino - Album on Imgur, What is the little yellow piece on left up side?

I try this too, and doesn't work.

Some one can give me a light about this?

Sorry for the bad english.

Thanks!
