There is something wrong with the breadboard, definitely. It is a brand new and this is indeed my first ever thing with electronics in general
I did some testing with the pin #2 jumper wire going to the ground, and I noticed that there was a spot where the V of pin #2 changes from 0V to 12.3V. Exactly in the middle of the breadboard. If it was on the left side, 12V, and if on the right side, 0V. This isn't supposed to be the kind of board that splits from the middle, but could it be one nevertheless?
Here's a pic of the true situation, I didn't tell you this previously, because I honestly thought it would matter. You see, the breadboard is in reality twice the size, and I just showed half of it in the previous illustrations. The ground and the positive line from the 12V battery are on the far right end. I also tested this with a jumper wire in the middle, and when that was included, LEDS 2-8 lit up immediately when powering up.
