AnalogWrite() Tinker example not working

Hi guys, I’m really exited to try this, it is my first programing of this sort but I’m a fast and thorough learner so bear with me

I got the photon kit and started following the getting started page but I don’t know why I can’t light up the included red led on the step 4

I have two boards, so I’ve tried 2 led and the 4 resistors, including using different places on the breadboard and nothing,

I think I’m missing something really stupid here, please help!

Are you sure your LED is placed correctly? There’s a + and - side on those things. Try double checking that.

Just to make sure you are talking to the correct device, can you turn on the blue onboard LED with digitalWrite D7?

Can you also provide a pic of your wiring?
