Lol, yeah... Its a part number, I never speak in leet unless making fun of something.
Lol, look at this leet version of google...

HK-47, What do you mean by. . .
Well its a lm317t not a 7805, its an adj. reg...

Obviously your calling out a part number for an adjustable regulator, but where does this apply? Is this what's used at this point in this project, or did I miss something?

I mean its not by default a 5volt regulator. All those components around it determine its output voltage. If you changed the value of those caps and resistors, the output voltage would change. Im just saying it might have a different pinout because its not a 7805, because its a different part all together.

HK is right. It is a LM317T. I looked at the page. I can see how you could get confused though, because earlier in that section, he calls it a 7805.

ah, I was under the misconception that it was a 7805....

Bottomline then, is there any difference in using either of the two for this part of the project?

yes!!! use the adjustable regulator rather then the 7805 and it should work
