.lesson # 2...thanks.

This would have Destroyed your Arduino chip pin's if you would have left it for a prolonged period enough.

attached see the diag. to understand the electrical connectivity, after that Please! visit google.com and search for BreadBoard tutorials.

ok i recently had a lab class with digital logic chips. REALLY COOL! I made an XOR equivalence with NAND gates (picture 1). I totally forgot about the connections on the breadboard since I haven't played with it in a while (since fall quarter). I don't have many 330 resistors so I want wondering if I could do this connection (picture 2). I wanted to ask before I screw up my arduino any more.

No!

OK!!..Thanks! Why so? it would help to get an explanation on why this wouldn't work. Thanks!

You have LEDs in parallel and in series, and some other issues, it looks.

Here's what - Is it possible that you could sketch out what you have in mind to do, take a picture of that composition, and then post that here?  Schematics are where it's at.

You don't need an Arduino to test out your creation there. 
Just use 5V to the/its input, thereby simulating an Arduino output, and no innocent Arduinos get hurt. 
But, don't do that anyway.

Horizontal and vertical are subjective depending on how you are viewing your breadboard.

On your breadboard, excluding the rows of power rails (the red and blue lines), the rows that are identified by letters are NOT connected together, the columns that are identified by numbers ARE connected together.  Each column of 5 holes are connected together, the long rows are NOT connected together.
