to make your own battery connection. Use pin D6 for the NeoPixel library code—all other
pins are available for other uses and have two breakouts on either side so you can wire up
other sensors or devices.
The ring kit comes as a single, round printed circuit board (PCB) with 24 individually
addressable RGB LEDs assembled and tested, two 12-pin 0.1-inch socket headers, and a
bonus JST cable. Some light soldering is required—you can solder the two sockets in
place to allow unplugging of the Photon, or just solder it directly in place for a slimmer
look.
Summary
Hopefully you can see that there are many ways in which your projects and experiments
can be simplified by using some of these add-on boards and shields. In the next chapter we
will take a look at using the “if this then that” (IFTTT) Web service with your Photon
board.
