Snap Circuits
®
uses building blocks with
snaps to build the different electrical and
electronic circuits in the projects. Each
block has a function: there are switch
blocks, lamp blocks, battery blocks,
different length wire blocks, etc. These
blocks are in different colors and have
numbers on them so that you can easily
identify them. The circuit you will build
is shown in color and with numbers,
identifying the blocks that you will use
and snap together to form a circuit.
For Example:
This is the switch block which is green
and has the marking on it as shown
in the drawings. Please note that the
drawing doesn’t reect the real switch
block exactly (it is missing the ON and
OFF markings), but gives you the general
idea of which part is being used in the
circuit.
This is a wire block which is blue and
comes in different wire lengths. This one
has the number , , , , or
on it depending on the length of the
wire connection required.
This is a 1-snap wire that is used as a
spacer or for interconnection between
different layers.
To build each circuit, you have a power
source block number that needs two
(2) “AA” batteries (not included with the
Snap Circuits
®
kit).
When installing a battery, be sure the
spring is compressed straight back, and
not bent up, down, or to one side. Battery
installation should be supervised by an
adult.
A large clear plastic base grid is included
with this kit to help keep the circuit blocks
properly spaced. You will see evenly
spaced posts that the different blocks
snap into. You do not need this base
to build your circuits, but it does help in
keeping your circuit together neatly. The
base has rows labeled A-G and columns
labeled 1-10.
Next to each part in every circuit drawing
is a small number in black. This tells you
which level the component is placed at.
Place all parts on level 1 rst, then all of
the parts on level 2, then all of the parts
on level 3, etc.
Usually when the motor is used, the
fan will usually be placed on it. On top of
the motor shaft is a black plastic piece
(the motor top) with three little tabs. Lay
the fan on the black piece so the slots
in its bottom “fall into place” around the
three tabs in the motor top. If not placed
properly, the fan will fall off when the
motor starts to spin.
Some circuits use the jumper wires to
make unusual connections. Just clip them
to metal snaps or as indicated.
Note: While building circuits, be
careful not to accidentally make a
direct connection across the battery
holder (a “short circuit”), as this may
damage and/or quickly drain the
batteries.
