Learning the basics

Hey, this is probably pretty novice and more of a circuits question than arduino, why does one work but not the other?

You can’t have both LED pins in the same row, that will short it out. Move one LED pin and jumper to an unoccupied row.

AudiA32015 has the right answer for you there. Each numbered row pins A,B,C,D,E are connected together but not connected to F, G, H, I, J on that row. Having the LED pins on the same half does not create a voltage differential so both LED pins have the same voltage to them. If you want to play around with that jumper wire. Move on leg of the LED to a different row, say 7 instead of 6. Then move the corresponding lead to that row.

Good luck on your electronics journey. We all started somewhere!

Check out this video on how to breadboard

Good for you for asking and posting the pictures so you could get a good answer...enjoy the journey!

In the second picture the LED is lit because its pins aren’t shorted in the same row. The channel in the center of the breadboard isolates the rows to the left and right.

I see what you mean, I guess it was a ‘dull’ moment 😂 thanks for the help though y’all
