So im pretty new to hardware stuff and bought a Pico W. I followed this tutorial and it kind of worked.
The blue cable goes from Pin 2 to the LED, the led to the resistor and the resistor over the purple cable to grounding.
However in the tutorial, the direction of the cable was exactly the other way around, but this did not work for me in any way.
Configuration i listed above and without header Pins -> the LED shines
I also tried other starting Pins(of course activated) and Grounding pins but this doesnt seem to be the issue.
Is there anything different with the Breadboard and grounding ? Or is there anything im doing fundamentally wrong ?
