GLOWING PIN
1
If you are using one of SparkFun’s pre-made designs, hold the design over the felt,
and use a fabric marker or chalk to mark where the LED should be placed to shine
through. Snap one LED off the LED panel.
Before attaching the LED, rotate it so the (+) and (– ) symbols on the LED board align
with the (+) and (–) symbols on the battery holder’s sew tabs. Use a small dab of hot
glue on the center of the front of the board to secure to the felt.
Be careful not to cover the holes with glue – we’ll need those to sew through later.
Do not put your battery in yet.

Make sure
your battery is
not installed in
the battery holder.

For this project only, we’ll place the LED with the
lens facing the felt, allowing it to shine through to
the other side. The back of the LED has a cursive
L, which should be facing you. For the rest of the
projects in this book, we’ll install the LED with the lens
up (away from the felt).
