HELP Wanted:-)
We had a first workshop using Adafruit Gemma + Neopixel Ring 16 RGB Led on Friday. Following the instructions on Adafruits webpage for Neopixel Ring earings. Before soldering we tested the gemma and rings. At first all seemed to work but shortly 4 out 20 rings stopped functioning. And after soldering the ones left we have now encountered more problems.
In the last one tried 4 leds out of 16 follows the code - the rest does not seem to do anything at all.
I have written to the support on Adafruit but so far no response. Sligthly discouraged and we have a presentation to the entire company in two days. Apart from the fail with Neopixel Ring the workshop was a great success and 16 people whom never tried code in their life was filled with inspiration of what you can do with an Arduino:-)
