Picture of soundie: a musical touch-sensitive light-up hoodie
This tutorial will show you how to create a garment that changes its behavior depending on how conductive you are. It detects conductivity through iron-on conductive fabric that we will use, and it will light up and sing different notes depending on how you touch the conductive fabric. We'll be using sewable electronics (the LilyPad arduino module) and conductive threads and fabrics so that your garment will be soft and washable.

Step 1: Supplies

Picture of supplies

You will need:

-- LilyPad Arduino main board
-- LilyPad USB Link
-- mini USB cable
-- LilyPad power supply
-- 12 LilyPad LEDs
-- speaker
-- a spool of 4-ply conductive thread
-- conductive fabric
-- a digital multimeter
-- a piece of clothing (I used a hoodie)
-- a needle
-- a fabric marker or piece of chalk, a bottle of fabric glue
(Available at your local fabric shop or Joann Stores.)
-- a pair of scissors
-- an iron
-- nail polish

I liked your project because I got a thought that it would help me with mine. I need to make flexible touch sensors. I was all like 'oh, cool let's do this!'. I read the code carefully, your instructions about stitching, started doing things finally but couldn't understand how the fabric sensor supposed to work if it's connected with a single wire and THEN..... i payed attention to the phrase "how conductive you are" !!

So, basically you run electricity through your body(!!) when you touch both pieces of fabric to close the circuit. It's very low voltage of course but is it fine still? What if someone has heart stimulator or something?

And i guess this works with the bare skin only and two pieces of fabric...

Don't get me wrong i still like the project :)

....just found some minus points

I want to make this project but I was wondering where you got the speakers from, and what are the details of the speakers used here (model number...etc). I am having troubling sourcing speakers so it would be great if someone could help me!

Hi, can I use a Lilypad Simple Board instead of the main board?
kanjun (author)  jgomula2 years ago
Yup. Just be sure to modify the code to map to the correct numbered pins.

and can I also get http://littlebirdelectronics.com/products/lilypad-arduino-328-main-board for main board and breakout
kanjun (author)  nmerannage13 years ago
Yes, that looks fine.

-do we have to use
LilyPad Arduino main board
LilyPad USB Link
LilyPad power supply
12 LilyPad LEDs
or can we use different brands than lily pad

for led, power supply does it have to be lily pad
kanjun (author)  nmerannage13 years ago
You can certainly use non-LilyPad microcontrollers and sensor components, as well as LEDs and power supplies. However, the useful thing about the LilyPad is that it's light-weight, lies flat, washable, and easy to sew into fabric.
oh mah gawd! OvvO I must build this awesomeness!

seriously, I have got to build this! just because i should, ya know?

what kind of speaker did you use?

Wow...really good!

What would it take for you to marry me?! :P

Actually...how or where did you learn all this stuff? :)

Fantastic, I love it! i was going to make a turn signal jacket using my Lilypad I just got, but now I may have to do something more like this.
