Preparing the wire pieces
Take a careful look at the short and long
wire pieces. You can see that the wire is
surrounded by a thin layer of plastic, know
as "insulation." The insulation prevents
current from being conveyed to your body,
for example, if you accidentally touch the
wire. There are cuts through the insulation
near both ends of the wire, forming loose
sleeves that you can easily slide off,
Bending the LED terminal wires
You will also have to bend the LED
terminal wires to be able to insert them
into position later on. To do that, proceed
just as you did with the wire bridges: Place
the LED on top of the sketch to the right,
and bend the wires as shown in the
drawing. Please note that one of the LED
terminals is shorter than the other. This
helps to tell them apart, which is
important because the LEDs will only light
up if they are installed in the right
direction.

leaving bare wire ends behind. The two
bare wire end sections should be equally
long, as shown in the picture below. Then,
you will still have to bend the wire pieces
into shape. To do that, place them so they
fit exactly on top of the sketch, and bend
them as shown:
