Music Sync RGB Wearable Spike (Arduino)

"This RGB Spike is created from the LED Stego Flex Spike Hoodie by Becky Stern. Follow this link to his design on Adafruit.com. "

Dress up with this RGB LED Spike that you can custom your own color and style. Also, it can sync with your music to make it ever cooler! All the component are all tied with one backstrap, with a battery that power hours of shiny fun. These hollow 3D printed Spike are transparent to diffuse LED.

Here are the material you need to create this fabulous spike by your self:

// -------------------------------------- Require material for RGB spike------------------------- //

3D Printed Spike ( Recommended wall size: 2mm ) - 20 pieces

WS2801 RGB led strip ( 20 LED, each one have an individual WS2801 chip)

Arduino Main Board

Backstrap

3m Double Sided Tape

Hot Glue

USB battery pack

Single core cable and Dupont Line

Pins - 40 pieces

// -------------------------------------- Require material for sync music ------------------------- //

1uf Capacitor - 1

1k ohm resistor - 1

3.5mm audio jack 4 pole male to 3 pole female (Not require if your playing device is 3 pole 3.5 mm audio hole)

3.5mm audio jack 3.5mm 3 pole audio jack splitter

A playing device ( Mp3, phone, etc.... )

The WS2801 chips are communicating with SPI, so find your strip's library, SPI.h library and instill it.

Hot glue each spike on to the LEDs

Connect the input of the strip with the Dupont Line ( 4 lines )

Red --> 5 volt --> 5 volt on the Arduino board

Yellow --> GND -- > GND on the Arduino board

Green --> Data pin ( MOSI ) --> Arduino digital pins

Blue --> Clock pin ( SCLK ) --> Arduino digital pins

Stick the Arduino board on the center platform of the back strap

Connect the four wire from the LED strip and two Single core cable to the Arduino

One cable to GND, one to Analog

Hide the cable at the back of the black strap

Attach the led strip with the spike in to the backstrap.

--> Use the pin to attach the wire to the black strap

--> Use some hot glue if it is not stable enough

The strip should start from one side of the shoulder and end on the shoulder on the opposite side.

The bottom of the spike should be the middle of your strip, which is number 9 and 10.

number = address of the led

Left shoulder ----------------------------------Right shoulder

-------------0 -----------------------------------------19

------------------1 ---------------------------------18

--------------------2 ---------------------------17

-----------------------3 -------------------16

---------------------------4 ----------15

--------------------------------5 14

--------------------------------6 13

--------------------------------7 12

--------------------------------8 11

--------------------------------9 10

Cut one output wire of the 3.5mm audio jack splitter, and pull out the GND and the audio line

Create the circuit following the top diagram with the GND and audio line of the wire.

Plug in the 4 pole to 3 pole audio jack into the audio splitter and connect the 4 pole side to your device

Note: If Arduino didn't read the audio, remember to turn your volume to the loudest so the single will stay from 0.1 volts to 1 volts so Arduino can read

Load the following script to the Arduino Script Here

This sync the music with the Arduino and the LED spike

Now power your Arduino with the battery pack, and there should be a startup animation to make sure all of the led is working correctly. It should start from the bottom of your spike.

To change the color of the Music sync spike: Change the following place in the script

Color(R,G,B)

Color of the audio display

Line 43: SoundToLed(SoundToLedAmount,Color(232, 100, 255)); Change the color's r g and b value

Color of the background

Line 68: c = Color(30, 200, 200); Change the color's r g and b value

To change to other display mode:

Remove: Line 43: SoundToLed(SoundToLedAmount,Color(232, 100, 255)); Turn off the music sync

Open: effect options

colorWipe(Color(232, 100, 255), 150); Set your color to create a wiping effect

rainbowCycle(10); Want some rainbow? Try this. The number is the duration

flashRandom(5, 8); Create some random color with this.
