Before you can actually start,
there are still a few
preparations you have to take
care of. One is to mount the
contact clips onto your board.
You will also have to insulate
off the wire sections and bend
them into the right shape. The
LEDs will have to be prepared
before inserting them in the
contact clips, too.
Mounting the contact clips
In order to assemble an alarm system or a
lie detector, you will have to be able to
connect the individual components to one
another. That is what the contact clips are
for. These are small, highly conductive
metal parts with holes in the top. You can
insert the components’ terminal wires or
connecting wires (the wire bridges) into
the holes and pull them out again easily.
Your kit contains 17 contact clips to insert
into the board. It’s easy. Just hold the sides
of the contact clip between thumb and
forefinger and press them gently together.
Then, simply insert the sides into the
openings. When you insert the clip, be
sure that the side with the holes is always
toward the top. If there are components
that you don’t need right away, you can
keep them in the top compartment and
the recesses to the right. The battery goes
in the compartment next to the area with
the contact clip openings.
