The hardware design was referenced to:

https://www.instructables.com/id/Music-Reactive-De...

Modifications:

1. Added the rule of frequency determine the color

2. Shift the sensing frequency to a higher pitch

3. decrease the sensitivity in detecting noises

The project was to create a music reactive light only for music. The project added frequency features to change light color due to different frequencies. The version decreases its sensitivity so it can concentrate on the music, not noise.

The program is the soul of a project. To have a project well planned, we must start with the code. Download the code, load the code into an Arduino Nano.

You may choose different variation of static electric stickers. Or just use a frosted acrylic pipe instead. In my case, I use a static electric sticker.

1. Wrap the acrylic tube with one layer of sticker.

2. Cut the sticker to suitable size.

3. If the sticker is insecure, tape the sticker with transparent tape.

With your circuit done, seal every metallic surfaces that exposed to air with electric resistant tape. Carefully push the Arduino Nano in first, and microphone the last.

1. Circle the cylinder with led strip, and secure it.

2. Put the cylinder into the acrylic tube.

3. Cut down two pieces of circular cardboard, stick into two sides.

1. Use any three identical structures as stand

2. Cut down a small piece of circular cardboard, stick it on the top hole.
