[Click here to buy a set of small alligator clip test leads.](http://adafruit.com/products/1008 "Link: http://adafruit.com/products/1008") ![flora_1008_LRG.jpg](https://cdn-learn.adafruit.com/assets/assets/000/003/512/medium640/flora_1008_LRG.jpg?1396797553) ![flora_1060_LRG.jpg](https://cdn-learn.adafruit.com/assets/assets/000/003/513/medium640/flora_1060_LRG.jpg?1396797557) **Snaps (optional)** Snaps can be used for quick-connecting circuit boards. You can sew them with conductive thread and/or solder them to circuit boards. [Click here to buy 5mm tin-plated brass snaps.](https://www.adafruit.com/products/1126 "Link: https://www.adafruit.com/products/1126") [Check out our guide to using snaps with Flora!](http://learn.adafruit.com/flora-snaps) ![flora_1126card_LRG.jpg](https://cdn-learn.adafruit.com/assets/assets/000/003/515/medium640/flora_1126card_LRG.jpg?1396797572) ![flora_1126insitu_LRG.jpg](https://cdn-learn.adafruit.com/assets/assets/000/003/516/medium640/flora_1126insitu_LRG.jpg?1396797581) # Flora GPS Jacket ## Build it ![](https://cdn-learn.adafruit.com/assets/assets/000/003/519/medium800/flora_gps-jacket-diagram.jpg?1396797612) Here's a diagram of the jacket's circuit. You'll chain eight pixels together around the collar and attach the GPS to 3.3v, TX, RX, and ground. A 3xAAA battery holder hides in a pocket and extends through a seam to plug into the JST port on the Flora. Make the connections in your circuit with conductive thread. ![flora_DSC_0103.jpg](https://cdn-learn.adafruit.com/assets/assets/000/003/520/medium640/flora_DSC_0103.jpg?1396797635) http://www.youtube.com/watch?v=XT5ygUt8Cbk Follow our [guide on conductive thread](http://learn.adafruit.com/conductive-thread) so you can stitch up your circuit like a pro! Start by stitching the ground bus from GND on Flora to the (-) pads on each pixel. Next stitch the power bus from VBATT to all of the (+) pads on your pixels. ![flora_DSC_0115.jpg](https://cdn-learn.adafruit.com/assets/assets/000/003/521/medium640/flora_DSC_0115.jpg?1396797653) ![](https://cdn-learn.adafruit.com/assets/assets/000/003/522/medium800/flora_Screen_Shot_2013-01-09_at_1.29.05_PM.png?1396797712) Then connect up the short data connections between each pixel. Be sure to seal the knots with clear nail polish or Fray Check. ![](https://cdn-learn.adafruit.com/assets/assets/000/003/524/medium800/flora_Screen_Shot_2013-01-09_at_2.19.24_PM.png?1396797844) Attach the GPS next! You can sew it directly to your garment or make it snappy with our Flora with Snaps tutorial. Connect 3.3v on the Flora to 3.3v, GND to GND, and RX-\>TX and TX-\>RX. You can hide the conductive thread traces just under the top layer of fabric, just make sure the stitches aren't so long that they can move and come into contact with each other. You can see that the thread periodically appears on the outside of the garment to anchor the stitched lines. You can optionally sew a coincell battery holder on the inside of the garment, connecting + to BAT on the GPS and - to GND. This will help the GPS get a fix on your position faster, since it can keep track of its last known position even when the device is off. ![flora_Screen_Shot_2013-01-09_at_2.24.49_PM.png](https://cdn-learn.adafruit.com/assets/assets/000/003/525/medium640/flora_Screen_Shot_2013-01-09_at_2.24.49_PM.png?1396797889) The battery holder is hidden in a pocket, with the JST connector poking out through a seam to connect to the Flora. If your pocket is far away from your circuit, Use one of our [handy JST battery extension cables](http://www.adafruit.com/products/1131). # Flora GPS Jacket ## The Code The code for the Flora GPS Jacket is pretty simple and straightforward.  We are using the standard Adafruit GPS Library, and the NeoPixel Library. In modern Arduino IDE versions, go to the Arduino Library Manager and select the following libraries to load: - Adafruit GPS Library - Adafruit NeoPixel Library. If you are using versions of the IDE older than 1.5, links to the code for the libraries are below. Click the buttons below to download. [Download the Adafruit GPS Library](https://github.com/adafruit/Adafruit-GPS-Library) [Download the NeoPixel Library](https://github.com/adafruit/Adafruit_NeoPixel) ![](https://cdn-learn.adafruit.com/assets/assets/000/003/526/medium800/flora_Screen_Shot_2013-01-09_at_1.41.36_PM.png?1396797951) Follow the [Flora Sewable NeoPixel tutorial](http://learn.adafruit.com/flora-rgb-smart-pixels) for more information about installing the library. Test out the pixel sample code to be sure your pixels are functioning properly. Next follow the [Flora GPS tutorial](http://learn.adafruit.com/flora-wearable-gps/) to test out your GPS module. To make sure your GPS has a direct view of the sky, dip your jacket out the window (but don't let it fall out!). I used a USB extension cable so I could have the jacket out the window but still plugged in to the computer! If both your pixels and your GPS module are working perfectly in your jacket circuit, click the Download File button below to get the code for this project: https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Flora/Flora_GPS_Jacket/Flora_GPS_Jacket/Flora_GPS_Jacket.ino ![](https://cdn-learn.adafruit.com/assets/assets/000/003/528/medium800/flora_Screen-Shot-2013-01-09-at-2.41.png?1396798013) Unzip the package and drag the Flora\_GPS\_Jacket folder into your Arduino folder (located by default in Documents on OS X). Open the enclosed **Flora\_GPS\_Jacket.ino** file in the [Adafruit Arduino IDE.](http://learn.adafruit.com/getting-started-with-flora/download-software) ![](https://cdn-learn.adafruit.com/assets/assets/000/003/529/medium800/flora_Screen_Shot_2013-01-09_at_2.46.01_PM.png?1396798047) The code is easy to modify for your own waypoint and range of sensitivity. Adjust these variables to your own preference. We like [GetLatLong.Net](https://getlatlong.net/) for finding latitudes and longitudes online. Upload your customized code to your jacket. # Flora GPS Jacket ## Wear it! ![](https://cdn-learn.adafruit.com/assets/assets/000/003/530/medium800/flora_gps-jacket.jpg?1396798079) Wear your GPS jacket with pride! Try changing the colors for different types of notifications, and make this project your own. We like to wear the Flora board on the outside of our jackets so we can show it to people and talk to them about it, but you can just as easily hide the main board inside the lining. The GPS, however, must be facing outward to have direct line of sight to the sky. To wash the jacket, simply remove the batteries. All other components can get wet while off, but should be thoroughly dry before powering back up. ![](https://cdn-learn.adafruit.com/assets/assets/000/009/292/medium800/flora_justine_allthethings.jpg?1396887051) ## Featured Products ### FLORA GPS Starter Pack [FLORA GPS Starter Pack](https://www.adafruit.com/product/1090) Get started with the fabulous Adafruit Flora platform with this lovely starter kit.
