Understanding Your Circuit
Take a look at the LED and battery holder. Notice that the silver sew tabs are labeled
either positive or negative. Many electronic components have polarity, meaning
electric current can only flow through them in one direction.
If hooked up incorrectly, they either will not work or will break. The batteries in this kit are
also polarized; they have a positive and negative side. Always check the labels on LilyPad
pieces to make sure they are correctly oriented before sewing together a circuit. In this
circuit, the LED is installed facing the fabric to shine through the other side. This only
happens for Project 1; the rest will have the LED facing away from the fabric.
