This is a project that I created for a Digital Multi Media class that I'm taking. I did it in hopes to notify my dad when he is being too loud. He's been a musician all of his life and due to this he can no longer hear as good as he used to. So hopefully now he can see how loud he is!

Step 1: Materials and Tools


-Arduino Uno-
-Electret Microphone Amplifier -
-Adafruit NeoPixel Digital RGB LD Weatherproof Strip 30 LED (1 meter) -
-6x AA Battery Holder

-Electrical  Tape
-Soldering Iron
-Zip Ties

Housing (optional)
- 20 in Paper Lantern

Step 2: LET'S DO IT! (wiring)-microphone

I started off by soldering the pins into the microphone and then connecting colored wires to them. The out pin is connected to the orange. The GND pin is connected to the red wire. The VCC pin is connected to the green and black wire. These are split to go into the 3.3v pin on the Arduino and the AREF pin.

Step 3: LET'S DO IT (cont.)-LED

I cut about four inches of colored wire and soldered them to the GND, DIN and +5v. 

Step 4: GO To Your HOME!

For my housing I used a 20 inch white paper lantern. You can choose whatever you would like. Let those brain juices flow!! Inside the lantern there is a frame that I connected my LED strip to using zip ties.

I connected my 6x AA battery pack to the bottom of the farm and placed my Arduino on top of that. I also attached my Arduino with a zip tie. 

Step 5: All of the Wires!

For my microphone I connected the OUT pin to the A5 pin on the Arduino. GND went into GND. VCC pin was split into two. One pin went into 3.3v and the second went into the AREF. 

For the LED's I connected GND to GND. DIN was connected to pin 6 and 5v to the 5v pin. 

DIN on the LEDS shows which way the flow is going. You can alter the pin number in the code. It's worked fine for me.

anyways to plug the cut off headphone jack to the arduino and not use a micophone ?

Hi I think this project is great, thanks very much for sharing! I can't currently get hold of the 30-led strip, would many amendments need to be made for a 60LED strip? thanks!

That's a useful project for schools, workshops, and anywhere that noise monitoring might be helpful. Thanks for sharing, and I hope you got top marks for the project.
