Couple of beginner questions

Yes that is one of the weaknesses of the solderless bread board. It looks like the maker of that one started with the display and connected resistors to it and then just wired the other ends to the Arduino outputs. Then they didn’t have the skill to make the resulting diagram easy to follow.

Thing is that the pin numbers are not important and can be juggled about to produce a diagram that is much easer to follow. The the correct numbers can be assigned in software.

That is the weakness of the Fritzing system, once a person reaches the skill level to produce good results then they also know it is a dead end with regards to conveying what the actual circuit is, especially when trying to communicate it with others.

Actually I got accused of being a misogynistic by a “semi famous maker” for suggesting that beginners would be better off if they didn’t use it. How she reached that conclusion from that fact is beyond me. I was instantly blocked so I could not discuss the matter. I think that is what is called un-platforming these days.
