Hump day peak VU meter project. I found some code on the internet, here: http://www.slickstreamer.info/2014/07/led-bracelet-vu-meter-3dprinting.html
I just had to try it out. In the video I adjust a knob, which controls the noise floor and either shows more or less LED’s. I am using an Adafruit MAX9814 breakout board at 40db gain, a Bluefruit Ez Link for wireless programming, 21 Neopixels and an Uno.
The music is from my Soundcloud account: https://soundcloud.com/jonburroughs/tracks check it out!
