LilyPad Coin Cell Battery Holder - Switched - 20mm

This is 12 meters of smooth conductive thread spun from stainless steel fiber and wound on a plastic bobbin. Use it to sew up all of your e-textile projects. This small bobbin is a great way to get into wearable electronics without the upfront cost of buying an entire spool of thread. Close to 40 feet of thread is enough to get a simple design stitched onto your shirt, backpack or hat. What sets this thread apart from the other conductive thread that we carry is the fact that it’s actually spun from 12UM stainless steel fiber making it incredibly smooth and without the loose hairs seen on other bobbins. This means that while it may not be easy to solder to, because it’s stainless, it also won’t burn up when you touch it with a soldering iron. Suitable for hand or machine sewing (as a bobbin thread). We’ve had no trouble using it for close, tight connections, but if you’re worried, waxing the thread should keep it manageable!

Detecting temperature changes has never been easier. The MCP9700 is a small thermistor type temperature sensor. This sensor will output 0.5V at 0 degrees C, 0.75V at 25 C, and 10mV per degree C. Doing an analog to digital conversion on the signal line will allow you to establish the local ambient temperature. Detect physical touch based on body heat and ambient conditions with this small sensor. LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They’re even washable! Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

The ProtoSnap series is a new way to prototype your project without a breadboard. Everything is wired together on a single board, which makes it easy to explore the possibilities of the components before snapping them apart and building them into your project. The ProtoSnap LilyTwinkle board is a very simple way to jump right into e-textiles. By including the LilyTwinkle, a coin cell battery holder (with built-in switch), and four white LEDs the ProtoSnap LilyTwinkle board easily allows you to add some sparkle to any project. To make your e-textile experience all the more enjoyable we have added a needle set and 30 feet of conductive thread! Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles and also to Arduino LLC to help fund continued development of new tools and new IDE features.

The LilyPad Sewable Electronics Kit lets you explore the wonderful world of electronic sewing (e-sewing) and e-textiles through a series of introductory projects using the LilyPad system. You’ll learn how to sew basic circuits to light up LEDs, control them with buttons and switches and even experiment with a pre-programmed LilyMini circuit that reacts to ambient light levels. In addition to LilyPad LEDs and battery holders, the kit comes with two LilyPad ProtoSnap boards that let you explore the circuit before you sew the pieces into a project. The full-color LilyPad Sewable Electronics Kit Guide (included) contains step-by-step instructions for using LilyPad pieces to create four complete sewable circuit projects with conductive thread. Easy-to-follow diagrams and troubleshooting tips make this a great introductory resource for crafters and creatives. LilyPad is a wearable technology developed by Dr. Leah Buechley and cooperatively designed by Dr. Buechley and SparkFun. Each LilyPad component was creatively constructed with large sew tabs to allow for stitching into clothing. Various input, output, power and sensor boards are available. They’re even washable! Note: A portion of this sale is given back to Dr. Buechley for continued development and education in e-textiles.   Sewable Electronics Projects: Project 1: Glowing Pin Project 2: Illuminated Mask Project 3: Light-Up Plush Project 4: Night-Light Pennant

This is the LilyPad Rainbow LED strip, with seven LilyPad LEDs that are still attached to one another, letting you snap LEDs apart at your leisure to sew into clothing or whatever else you can dream up. The LilyPad Rainbow LED features seven individual LEDs in six unique colors (Red, Blue, Green, Yellow, Pink, and White). Text has been added to the back of each board to indicate its color. Due to popular request, we have included two white LEDs instead of just one. Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education in e-textiles.

The LilyPad ProtoSnap Plus is a sewable electronics prototyping board that you can use to explore circuits and programming, then break apart to make an interactive fabric or wearable project. Programming the ProtoSnap Plus is easy with the free Arduino software you’ll need to program the ATmega32U4 on LilyPad USB Plus at the heart of the board. Once you’ve installed the software, you’ll be able to write and upload your own programs to the board, making it do almost anything you want. At the center of the ProtoSnap Plus is the LilyPad USB Plus microcontroller, pre-wired to a LilyPad board including a LilyPad Light Sensor, LilyPad Buzzer, LilyPad Button Board, four pairs of colored LilyPad LEDs and a LilyPad Slide Switch. Because these components are connected together on the ProtoSnap board, you can test out your project ideas before you sew. The ProtoSnap Plus also includes expansion ports that let you sew your wearables together or use alligator cables to easily connect external sensors and components. After testing out your coding ideas using the attached LilyPad pieces, you can break apart the prototyping board and sew them into your project! Please be aware that the Lilypad ProtoSnap Plus is NOT supported on Windows 7/8 due to a lack of support drivers for those specific OS’s. Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education in e-textiles.

The LilyTwinkle is a tiny little LilyPad board designed to add some twinkle to your project. Even though it's as small as some of the LilyPad sensors, this board actually has an ATtiny microcontroller on it so it's actually pretty smart! Simply sew on 4 LEDs and connect a battery and the LEDs will twinkle-fade (a lot like fireflies... or lightning bugs, if that's what you call them). LilyTwinkle is a quick and easy way to add twinkling lights to a project without any programming or a bulky Main Board. If you're an advanced user and want to re-program the LilyTwinkle, the ICSP programming connectors are broken out on the back. LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available.
