I leant this to the Bellaire High School Makerspace. It’s a sound meter based on a similar project from Adafruit. The Arduino-compatible Flora board reads the signal from the microphone and lights the strip of NeoPixel LEDs based on the level of sound. The brightness is also based on the sound level. Yes the knob goes to 11. You can control the max brightness with the knob.

Version 5: Flora-controlled VU meter. I added a brightness knob. At the highest setting (11) the brightness is based on volume. On all others the brightness is the setting of the knob 0-10. I think I’m done adding things. The song is Electric Feel by MGMT. the is based on the AmpliTie project from AdaFruit. https://learn.adafruit.com/led-ampli-tie/overview

Second iteration of VU meter using Arduino Flora, 15 NeoPixel smart LEDs, and an Electret microphone all from AdaFruit. The code is mostly theirs too honestly. Tomorrow perhaps I’ll solder that together on a perma-proto board. I still need to make the auto-gain work a bit better too.
