Step 4Wrist Band Setup
I am using the lilypad power supply (www.sparkfun.com/commerce/product_info.php). This device uses a AAA battery and has 3 minus holes and 1 plus hole. Stitch Minus on the Power Supply to Minus on the LilyPad and Plus on the Power Supply to Plus on the Lilypad.
Choose a fastener. I chose velcro because it's easy to sew down and you can adjust for arm width
