# LED Harness Bra
## Harness
In this part of the guide, you’ll measure and cut pieces of pleather to create a custom harness. This simple harness design is comprised of 6 pieces which I'll name for this guide: The halter, upper-horizontal, lower-horizontal, vertical, and a “V” (left & right) on top.
# LED Harness Bra
## Prep
## Halter Piece
Measure the distance from the left side of your waist, over your neck, and down to the right side of your waist. Label this piece and mark the halfway point.
## Upper Horizontal Piece
Measure around your body directly under your chest or wherever you’d like the upper horizontal piece to sit. Cut half of this length in pleather and the other half in elastic. Label and mark the halfway point on the piece of pleather.
## Lower Horizontal Piece
Measure your waist or wherever you’d like the lower horizontal piece to sit. Cut 2/3 of this length in pleather and 1/3 in elastic. Label and mark the halfway point on the piece of pleather.
## The "V"
I measured between where the halter piece hit my clavicle to where I wanted the V to hit the center of my chest. Add 1” and cut two pieces.
## Vertical Piece
Measure from your waistline directly up to the V. Add 1” and cut.
# LED Harness Bra
## Sewing Tips
Here are some tips on using pleather:
- If you can't find pleather trim, cut strips ¾” or 1” wide out of a non-stretch pleather fabric.
- Test sew two pieces of pleather trim together to determine the best needle, stitch settings, and tension for your machine.
- Use pins or a small piece of double sided tape to hold pleather together.
- When sewing the pleather together, you may need to use something as a stabilizer. [Tissue paper works great.](http://blog.megannielsen.com/2017/05/quick-tip-tissue-paper/) Note: I did not need stabilizer for the pleather trim, but I did for raw pleather.
# LED Harness Bra
## Construction
Start with the pleather and elastic for the upper horizontal. Overlap the two pieces by ½” & sew together.
Repeat for lower horizontal pleather and elastic.
## Attach halter to horizontal pieces
With the upper and lower horizontal pieces on your body or the dress form, center the harness halter piece over your neck.
Determine where the pieces should overlap. Attach with pins or a small piece of double sided tape between the strips of fabric.
Measure both sides off body to ensure things are still even and adjust accordingly.
Sew together. Try on and if there are any issues, pick the stitches out and try again.
## Attach vertical & V pieces
Align the one end of the vertical piece with the bottom center of the lower horizontal piece. Align the upper horizontal piece with the vertical piece, so that the horizontal pieces are parallel. Sew together.
Align one piece of the V just below the right clavicle. Pin together or use a small piece of double sided tape between the strips of fabric. Measure to determine the right location for the left piece of the V. Pin together or use a small piece of double sided tape between the strips of fabric.
Try it on again and attach to the vertical piece.
Trim any excess fabric or threads.
# LED Harness Bra
## Code
## Arduino IDE
Open your Arduino IDE. If you are new to Arduino, check out this guide: [Adafruit Arduino IDE Setup](https://learn.adafruit.com/adafruit-arduino-ide-setup?view=all).
This sketch uses three libraries: the FastLED library, the Adafruit Circuit Playground microphone library, and the Adafruit Arduino Zero / Feather M0 I2S audio library. See [FastLED.io](http://fastled.io/) for more information, the [FastLED github](https://github.com/FastLED/FastLED), or visit their [community on Reddit](https://www.reddit.com/r/FastLED/). You can learn more about Arduino libraries by [reading this guide from Adafruit](https://learn.adafruit.com/adafruit-all-about-arduino-libraries-install-use "All About Adafruit Libraries").
Download the Circuit Playground library if you haven't already done so. See the [Circuit Playground Express guide](https://learn.adafruit.com/adafruit-circuit-playground-express/overview) to learn more about the board. In this sketch, we'll utilize some of the supporting libraries used by the Circuit Playground.
## Code
Download the sketch in its entirety or take the following steps to ensure you have the right files for running the sketch.
Open a new sketch in your Arduino IDE & save it as a new folder. Find the folder just created by your new sketch. Copy & paste the following files from your Circuit Playground utilities folder into the newly created folder:
- Adafruit\_CPlay\_Mic.cpp
- Adafruit\_CPlay\_Mic.h
- Adafruit\_ZeroPDM.cpp
- Adafruit\_ZeroPDM.h
https://youtu.be/H1fY4w2-M6Y
Plug the Adafruit Circuit Playground Express into your computer with a USB cable, verify and upload the following code.
Once you have uploaded your code, test it out on your Adafruit Circuit Playground Express. Although it will think that there are more LEDs attached, click through the modes and test the switch to make sure it all works.

# LED Harness Bra
## LEDs
There are a few ways to approach stringing LEDs. This part of the guide will go over my method of braiding the three wires between each NeoPixel. This page provides an overview of the method covered in greater detail over the next few pages.
If you aren’t interested in braiding, [Erin](https://learn.adafruit.com/users/firepixie) has a great method for [quickly stringing NeoPixels together,](https://youtu.be/5r3g65XpdAA) shown in her twinkling LED parasol.
## Cut & Strip Wires
When cutting wires, determine the approximate distance between the LEDs & add at least 1”. Use a wire stripper tool or your fingernails to strip approximately ¼” off the ends.
## Make the Data Line
Start by connecting the data line between LEDs, ensuring that the arrows all point in the same direction!
## Power & Ground
Add power and ground wires. Use different color wires or mark wires to ensure that the lines don't cross. I attach power before ground wires and strip the ends of my power wires.
## Braid
Braid and solder wires to NeoPixels, starting with the power wires, before moving onto the ground wires.
# LED Harness Bra
## Circuit Diagram
Review the circuit diagram. This illustration is meant for referencing wired connections. The length of wire, position, and size of components might not match the actual project.
Info:
I've had success with this method with a small number of LEDs. For a larger project, you should review the voltage drop on the signals coming in to a _data in_. If the wires are long or go in too many directions, the signal may not be strong enough to drive the data along the strand.
This approach allows us to create a dimensional array of LEDs without doing extensive mapping: the LEDs on the right and left as well as the pieces along the waist and under the bust will show mirrored animations.
The sections of pixels will be reviewed in detail on the next page.
# LED Harness Bra
## Data Line
Start connecting the data line using the pieces of wire you've cut and stripped.
Work in the sections recommended to ensure that the data flows all in one direction.
# Sections
Sections 1 & 2 are identical and each contain 9 individual LEDs.
There will be two data lines out of the 4th LED on each side.
Sections 3-6 are identical and each contain 3 LEDs.
Section 7 brings together the NeoPixel ring, two NeoPixel Jewels & two individual NeoPixels.
The data in on the top jewel is fed from one LED.
There are 4 data out wires on the bottom jewel, one pointing towards each of the "sections" 3-6.
# Bring it all together
Attach two wires to the **A1** pin on the Circuit Playground Express (CPX) and connect it to the two NeoPixels at the top.
One of the wires will need to be long enough to travel under the CPX and to the first pixel on that side.
# LED Harness Bra
## Power & Ground
Start with one of the LEDs identified by a star in the image.
Determine the approximate distance between the ground and power holes on this and the adjacent LEDs.
## Wires
Cut wires at least 1” longer than the longest distance needed. You will need 4 wires for most of the LEDs, but 6 for LEDs where the data line is split.
Strip approximately ¼” off one side of each wire. If you are using different color wires, strip all sides at once.
Twist the stripped ends of wire into a pair or triplet so that it can fit into a hole on the neopixels
## Solder, Part 1
Attach one pair (or triplet) of wires into the power and the other pair into the ground holes of the LED.
Strip about ¼” off the ends of the wires in the power hole of the LED. If you are using different color wires, strip all sides at once.
## Braid
Braid wires from two LEDs towards an LED without any wires.
The 30awg wire will fit into the NeoPixel holes without being stripped. I found this was a great way to keep the braid on one side while braiding another set of wires or waited until another section was complete.
## Solder, Part 2
After braiding, check to ensure that wiring is correct from one LED to the next.
Strip any additional sheathing from the power wires, twist together, feed through the power hole, and solder.
Once the power wires are attached, strip ground wires, twist together, feed through the ground hole, and solder.
## Bring it all Together
The power and ground lines of the NeoPixels in Sections 3 & 4 connect directly to the power line on the NeoPixel Ring in the center. These NeoPixels also connect up to the top along the outside.
Follow the diagram to complete the rest of the power and ground wiring.
It may feel like a mess at some points. Remember to take breaks, double check your work, and say nice things to yourself!
Warning:
# LED Harness Bra
## Final Assembly and Wear
In a well ventilated space, dab solder joints with e6000 or other adhesive of your choice.
## Attach to Harness
Position the strand on the pleather harness. Dab e6000 adhesive onto the larger NeoPixel pieces and the LEDs that will sit on ends and corners and attach to the harness and clip into place. Use e6000 and thread to tack down the rest of the pixels.
## Battery Pocket
Print a [3D Printed Battery Pocket](https://learn.adafruit.com/mystical-led-halloween-hood/3d-printed-battery-pocket)for your Lithium Ion Polymer battery or sew a battery pocket out of fabric and attach to the side of the harness.
## Wear It!
Plug the battery into the extension cable and the CPX and turn it on.
Use the slide-switch to turn on and off the LEDs. The switch itself doesn't turn the board off, but allows you to go a little incognito with the lights.
Use the left button on the CPX to cycle through some FastLED examples. Customize your sketch by creating new modes and palettes!
Use the right button on the CPX to activate the pretty VU meter example sketch.
