Issues with a basic circuit I am having some issues with a simple circuit. I would expect this circuit to light up this LED constantly when the Arduino is plugged in. I have the Blink tutorial sketch loaded, but I don't think that should matter with the pins I am using.

This is what I think I have going on: Arduino 5V Power --> BB power --> 100 Ohm resistor --> BB line 25 --> this LED --> BB line 30 --> BB Ground --> Arduino Ground

Please check out this picture for confirmation:



Thanks in advance for any help that you can provide!
Figured it out - stupid mistake as expected. The power and ground lines on my bread board don't go all the way across. They break right in the middle, as the lines show. I moved my ground connection to the left a few slots and it worked. Thanks for working through it with me jfpoilpret!
