I had problems getting a connection to the gemma on my Win 8.1 laptop, so I switched to a flora. That worked.
For some reason I could only get the one NeoPixel Ring – 24 x WS2812 5050 RGB LED I had to work with 11 LEDs. It had been out in a store room and likely broke due to temperatures from 19-25F. Since I had only one ring that size, I chose to use the Wire Light LED Strand – 12 Green LEDs + Coin Battery holder in the right lens. Both from Adafruit.com.
I toned the brightness down to 25 out of 255 for the ring. These are photos of various colors from the ring. I used part of strandtest and another sketch. My laptop crashed, so I’ll have to dig around and find the sketch I used.
