Firewalker LED setup
Hi, I have tried the following test setup but it doesn't seem to light up the LED strip. Able to advise on the connection error?

Re: Firewalker LED setup
The first thing is to be sure you have good connections and your 'gator clips aren't shorting. You should use another ground pin rather than try to squeeze two clips on the one pad.
I do like how they have the wires taped down in the guide's test circuit so they don't shift around and mess things up.
Second is to verify that your connections agree with the code.
There's also the issue of powering the NeoPixels with 5v (from the USB in your photo) and driving it with a 3.3v signal which it looks like the Flora generates. This may or not be your problem, but you can try powering the NeoPixels with 3v and see if that helps. BTW, the onboard NeoPixel is powered by 3.3v so this sounds highly possible.
