How to make a Heating and Cooling Jacket

Step 2 Creating your liner

 

Most important phase of the jacket: sewing the liner (a.k.a. your control center)

1. Sew on your Lilypad Arduino to a safe spot. We placed ours on the front right side of the liner, right above the pocket.
      * Connect Lilypad to computer with the cable and USB given in the Pro kit. This way you will know if your lilypad is working, and you will be able to become familiar with it.

2. Sew in your on/off snaps and battery close to your Lilypad. Placing the battery inside of a pocket would be best, so if it falls off it will not get lost. Put the snaps inside the liner, between the battery and the Lilypad. 
     * Put the snaps in first, before sewing in the leads to the battery. This is important because this is how you will be able to turn your jacket on and off. SEE PHOTO

3. Connect your battery to your Lilypad. Sew on lead directly to Lilypad from the battery. Sew the other lead to the snaps. Then from the snaps sew to the Lilypad.
       * Make sure to connect the negative of the battery to the negative of the Lilypad and the positive of the battery to the positive of the Lilypad. (Labeled with a positive and a negative).
