Make sure your Photon is plugged into your computer and sign into Particle.io. Then, go into "Console" and make sure you've selected your Photon device. Next, go into the "IDE" and enter the code below. It's important to load the code before you get to the next step of "Finishing Touches" as a function is called that needs to be read by the program IFTTT (IfThisThenThat).
Make sure you have added the Adafruit NeoPixel Library in Particle Build for this sketch to work. Just because the code lists the library doesn't mean that it is seen. It will generate its own line of code.
/* ISS Pin by Leslie Birch for Adafruit Industries
Based on NeoPixel Library by Adafruit and code from Particle.io
This version connects with IFTTT and shows a ring of blue, white, red and multi when triggered.
When not triggered, it does a comet chase of white. */
