Sound reactive Neopixel + GEMMA not working Moderators: adafruit_support_bill, adafruit

Hi!

I've installed and tried to get the demo code in Arduino working for this project:

I use the Gemma v2 (1222) (DC powered) and Arduino 1.8.9 and the uploading works fine, no errors. But the sound reactive lights doesn't work, only two nieghbour LEDs and one LED further away on the strip has a steady light in red after I hit the drum once. And they are still lit after I have turned the DC power off.

Any suggestions?

Many thanks!
