@freddyroosevelt: As @peekay123 has pointed out, please do use exactly the pins as outlined in my post
So you even need to change the other three wires (not D0, D1, D2, D3, D4 on the Core, but A3, A5, D3, D4, D5)!
You could save yourself (and us) a lot of grief, if you follow instructions a bit more closely.
BTW:
As I see you happen to run a Particle Core and not a Photon.
It shouldn't make any difference for your current project, but it might be important to give the correct information for some future questions.
