Hi there, I have students creating a project based off of the sound reactive neopixel peace pendant
https://learn.adafruit.com/sound-reacti ... t/assembly and we wired it the same way as in the model, except
- we did not use the battery charger
we used the mic with gain and the other option, but only wired the out port as shown in the directions
The code loads into the gemma fine, but the lights don't seem to respond to sound, instead they turn on when we touch the metal on the gemma/components, specifically the ground.
Ideas?
