Understanding Your Circuit
This project is an example of a basic circuit – an electrical loop that travels from a
power source along a path (called a trace) to a component (or components) that uses the
electricity to function, and then back to the power source. For our project, we’ll use an LED
(Light-Emitting Diode). When this loop is completed by stitching the pieces together with
conductive thread traces, electricity from the power source is able to flow from the positive
(+) side of the battery through to the LED (lighting it up) and back to the negative (–) side
of the battery. This electric flow is called current. As you build the projects in this book, you
will learn different ways to design conductive thread circuits and experiment with additional
pieces that help control or use the flow of electricity. In this circuit configuration, the LED
is facing the fabric to shine through the other side.
