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, light blocks,
battery blocks, different length wire blocks, etc.
These blocks are different colors and have
numbers on them so that you can easily
identify them. The blocks you will be using are
shown as color symbols with level numbers
next to them, allowing you to easily snap them
together to form a circuit.
For Example:
This is the slide switch, it is green and has the
marking on it. The part symbols in this
booklet may not exactly match the appearance
of the actual parts, but will clearly identify them.
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.
There is also a 1-snap wire that is used as a
spacer or for interconnection between different
layers.
You need a power source to build each circuit.
This is labeled and requires three (3) 1.5V
“AA” batteries (not included).
One large and four smaller clear plastic base
grids are included with this kit to help keep the
circuit blocks properly spaced. You will see
evenly spaced posts that the different blocks
snap into. The large base has rows labeled A-
G and columns labeled 1-10, and the small
base has rows labeled A-E and columns
labeled 1-7. It should be obvious whether to
use a small base grid or a large base grid. For
small circuits that only need one grid, either
size may be used.
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 first, then all of the parts on
level 2, then all of the parts on level 3, etc.
Some circuits use the jumper wires to make
unusual connections. Just clip them to the
metal snaps or as indicated.
When assembling the 3D circuits, the order in
which parts are installed is important. In
particular, the vertical snap wires (V1) need to
be snapped onto the mini base grid first and
then the mini base grid is slid into the base grid
support as shown below.

Due to the complex nature of building 3D
circuits, the circuit diagrams use special
symbols that may need additional clarification.
One such example is the symbol for the
vertical snap wire (V1). It consists of two parts,
the horizontal base and vertical stem. In the
illustration below, the base is attached to the
large base grid and the stem is attached to the
mini base grid. The symbol makes V1 appear
as two separate parts, but in reality the symbol
is connected at the red circular ends.
Another symbol of note is the base grid
support. It is important to pay attention to the
orientation of the part in the diagram since it is
not symmetrical. The figure below shows the
symbol with the narrow channel on top. This
corresponds to the 3D rendering showing the
base grid support orientation.
When inserting the base grid into the base grid
support, it is a good idea to insert an area on
the base grid that doesn’t have raised letters
or numbers. The raised text can interfere with
the insertion or cause a tight fit between the
base grid and base grid support.
To install the base grid support onto the base
grid, align the holes of the support with the
base grid pegs in the desired location on the
base grid and press down firmly on the base
grid support. Make sure that the base grid
support is fully seated on the base grid.
The stabilizer is used to connect base grids on
their corners or edges. With eight slots, the
stabilizer allows the base grids to be mounted
in increments of 45 degrees. To attach the
stabilizer to the base grid, simply align the
desired grooves in the stabilizer with the edges
of the base grids and press down. The figure
below shows how the stabilizer symbol is
presented in the manual and the 3D rendering
of the stabilizer mounted to two base grids.
The mirror assembly consists of three parts:
the mirror, the mirror mounting base, and the
spring (sometimes the spring is not used).
Begin by connecting the spring to the mirror
mounting base. To achieve this, you need to
line up the large end of the spring with the post
on the bottom of the mounting base. Then, with
the mounting base in one hand and the spring
in the other, push the two pieces together while
turning the mounting base counter-clockwise
and the spring clockwise until it is fully seated
(see figure below).
When the time comes to remove the spring,
simply twist the spring clockwise while pulling
it away from the mounting base.
Next, remove the protective backing off both
sides of the mirror and align it with the groove
on top of the mirror mounting base. Press the
two parts together until the mirror is fully
seated and centered on the mounting base.

Note: While building the projects, 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.

BASE GRID
BATTERY HOLDER
The base grids are platforms for mounting parts
and wires. They function like the printed circuit
boards used in most electronic products, or like
how the walls are used for mounting the electrical
wiring in your home. This set has two sizes,
which can be placed together to form larger
grids.
SNAP WIRES, VERTICALSNAP
WIRES, & JUMPER WIRES
The batteries (B3) produce an electrical voltage
using a chemical reaction. This “voltage” can be
thought of as electrical pressure, pushing
electricity through a circuit just like a pump
pushes water through pipes. This voltage is
much lower and much safer than that used in
your house wiring. Using more batteries
increases the “pressure”, therefore, more
electricity flows.
Battery Holder (B3)
Slide &Press
Switches
(S1 & S2)
SLIDE&PRESS SWITCHES
The slide & press switches (S1 &S2) connect
(pressed or “ON”) or disconnect (not pressed or
“OFF”) the wires in a circuit. When ON they have
no effect on circuit performance. Switches turn
on electricity just like a faucet turns on water from
a pipe.
The blue snap
wires are wires
used to connect
components. They
are used to transport
electricity and do not affect
circuit performance. They come in
different lengths to allow orderly
arrangement of connections on the base grid.
The vertical snap wires
(V1) make connections
between two dimensions,
allowing electricity to go up
a wall.
The jumper wires (red, black, & blue) make
flexible connections for times when using the
snap wires
would be
difficult. They
also are used
to make con-
nections off the
base grid.
Wires transport electricity
just like pipes are used to transport water. The
colorful plastic coating protects them and
prevents electricity from getting in or out.
The horn (W1) converts electricity into sound by
making mechanical vibrations. These vibrations
create variations in air pressure, which travel
across the room. You “hear sound when your
ears feel these air pressure
variations.

TRANSISTORS
The NPN transistor (Q2) is a component that
uses a small electric current to control a large
current, and are used in switching, amplifier, and
buffering applications. Transistors are easy to
miniaturize, and are the main building blocks of
integrated circuits including the microprocessor
and memory circuits in computers.
NPNTransistor (Q2)
LIGHTTUNNEL
The light tunnel (U30) contains 3 red, 3 green,
and 3 blue LEDs, arrayed with mirroring effects.
When voltage is applied across the (+) and R
(or RED) snaps, the red LEDs light.
When voltage is applied across the (+) and G
(or GRN) snaps, the green LEDs light.
When voltage is applied across the (+) and B
(or BLU) snaps, the blue LEDs light.
When voltage is applied across the (+) and (−)
snaps, circuitry in it lights the LEDs in a
changing pattern.
Light Tunnel (U30)
LEDs
LEDs
(D6 &D8)
The white and color LEDs (D6 & D8) are light
emitting diodes, and may be thought of as a
special one-way light bulbs. In the “forward”
direction, (indicated by the “arrow” in the symbol)
electricity flows if the voltage exceeds a turn-on
threshold brightness then increases. The color
LED contains red, green, and blue LEDs, with a
micro-circuit controlling then. A high current will
burn out an LED, so the current must be limited
by other components in the circuit (Snap
Circuits
®
LEDs have internal resistors added, to
protect them in case you make wiring mistakes).
LEDs block electricity in the “reverse” direction.
The phototransistor (Q4) is a transistor that
uses light to control electric current.
Phototransistor (Q4)
RESISTORS
5.1kW Resistor (R3)
Resistors “resist” the flow of electricity and are
used to control or limit the current in a circuit. This
set includes a 5.1kW resistor (R3) (“k”
symbolizes 1,000, so R3 is really 5,100W).
Materials like metal have very low resistance
(<1W), while materials like paper, plastic, and air
have near-infinite resistance. Increasing circuit
resistance reduces the flow of electricity.

Introduction to Electricity
What is electricity? Nobody really knows. We only know how to produce it,
understand its properties, and how to control it. Electricity is the movement of sub-
atomic charged particles (called electrons) through a material due to electrical
pressure across the material, such as from a battery.
Power sources, such as batteries, push electricity through a circuit, like a pump
pushes water through pipes. Wires carry electricity, like pipes carry water. Devices
like LEDs, motors, and speakers use the energy in electricity to do things. Switches
and transistors control the flow of electricity like valves and faucets control water.
Resistors limit the flow of electricity.
The electrical pressure exerted by a battery or other power source is called
voltage and is measured in volts (V). Notice the “+” and “–” signs on the battery;
these indicate which direction the battery will “pump” the electricity.
The electric current is a measure of how fast electricity is flowing in a wire, just
as the water current describes how fast water is flowing in a pipe. It is expressed
in amperes (A) or milliamps (mA, 1/1000 of an ampere).
The powerof electricity is a measure of how fast energy is moving through a
wire. It is a combination of the voltage and current (Power = Voltage x Current). It
is expressed in watts (W).
The resistance of a component or circuit represents how much it resists the
electrical pressure (voltage) and limits the flow of electric current. The relationship
is Voltage = Current x Resistance. When the resistance increases, less current
flows. Resistance is measured in ohms (W), or kilo ohms (kW, 1000 ohms).
Nearly all of the electricity used in our world is produced at enormous generators
driven by steam or water pressure. Wires are used to efficiently transport this
energy to homes and businesses where it is used. Motors convert the electricity
back into mechanical form to drive machinery and appliances. The most important
aspect of electricity in our society is that it allows energy to be easily transported
over distances.
Note that “distances” includes not just large distances but also tiny distances. Try
to imagine a plumbing structure of the same complexity as the circuitry inside a
portable radio - it would have to be large because we can’t make water pipes so
small. Electricity allows complex designs to be made very small.
There are two ways of arranging parts in a circuit, in series or
in parallel. Here are examples:
Placing components in series increases the resistance; highest
value dominates. Placing components in parallel decreases the
resistance; lowest value dominates.
The parts within these series and parallel sub-circuits may be
arranged in different ways without changing what the circuit
does. Large circuits are made of combinations of smaller series
and parallel circuits.

DOs and DON’Ts of Building Circuits
Placing a 3-snap wire directly
across the batteries is a
SHORT CIRCUIT.
This is also a
SHORT CIRCUIT.
When the slide switch (S1) is turned on, this large circuit has a SHORT
CIRCUIT path (as shown by the arrows). The short circuit prevents any
other portions of the circuit from ever working.

Examples of SHORT CIRCUITS - NEVER DO THESE!!!
WARNING: SHOCK HAZARD - Never connect Snap Circuits
®
to the electrical outlets in your home in any way!
After building the circuits given in this booklet, you may wish to experiment on
your own. Use the projects in this booklet as a guide, as many important design
concepts are introduced throughout them. Every circuit will include a power
source (the batteries), a resistance (which might be a resistor, horn, LED (which
has an internal protection resistor), light tunnel, etc.), and wiring paths between
them and back. You must be careful not to create “short circuits” (very low-
resistance paths across the batteries, see examples below) as this will damage
components and/or quickly drain your batteries. Only connect the light tunnel
(U30) using configurations given in the projects, incorrectly doing so may damage
it. Elenco
®
is not responsible for parts damaged due to incorrect wiring.
Here are some important guidelines:
ALWAYS
USE EYE PROTECTION WHEN EXPERIMENTING ON YOUR OWN.
ALWAYS
include at least one component that will limit the current through a
circuit, such as a resistor, horn, an LED (which has an internal
protection resistor), light tunnel (which must be connected properly).
ALWAYS use switches in conjunction with other components that will limit
the current through them. Failure to do so will create a short circuit
and/or damage those parts.
ALWAYS disconnect your batteries immediately and check your wiring if
something appears to be getting hot.
ALWAYS check your wiring before turning on a circuit.
ALWAYS
connect the light tunnel (U30) using configurations given in the
projects or as per the connection descriptions for the parts.
NEVER connect to an electrical outlet in your home in any way.
NEVER leave a circuit unattended when it is turned on.
For all of the projects given in this book, the parts may be arranged in different
ways without changing the circuit. For example, the order of parts connected
in series or in parallel does not matter — what matters is how combinations
of these sub-circuits are arranged together.
3D Construction: Motors or other parts that produce motion (which you may
have from other snap Circuits
®
sets) should not be mounted overhead or on
walls, as the vibrations they produce could cause them to fall.

is not responsible for parts damaged due to incorrect
wiring.
If you suspect you have damaged parts, you can follow
this procedure to systematically determine which ones
need replacing:
1. White LED(D6), color LED(D8), horn (W1), and battery
holder(B3): Place batteries in holder. Place the white LED,
and color LED directly across the battery holder (LED + to
battery +), the LED should light. Similarly, place the horn
directly across the battery holder (+ to +), it should make sound.
If none work, then replace your batteries and repeat, if still bad
then the battery holder is damaged.
2.
Jumper wires: Use this mini-
circuit to test each jumper wire,
the LED should light.
3.
Snap wires: Use this mini-
circuit to test each of the snap
wires, one at a time. The LED
should light.
4.
Vertical snap wires (V1): Use
this mini-circuit to test each of
the vertical snap wires, one at a
time. The LED should light.
5.
Slide switch (S1) and press switch (S2): Build project 1; if
the color LED (D8) doesn’t light then the slide switch is bad.
Replace the slide switch with the press switch to test it.
6. Phototransistor (Q4) and 5.1kW resistor (R3): Build project
54 and vary the amount of light shining on the phototransistor.
The brighter the light on the phototransistor, the brighter the
color LED (D8) should be. Then replace the phototransistor with
the 5.1kW resistor; the color LED should light dimly.
7.
NPNtransistor (Q2): Use project 98; the white LED (D6)
should be on only if the press switch (S2) is pushed. If
otherwise then Q2 is damaged.
8. Light tunnel(U30): Use project 136 to test it.

Project 1
Color Light
Snap Circuits
®
uses electronic blocks that snap onto a clear plastic base grid to
build different circuits. These blocks have different colors and numbers on them so
you can easily identify them. This set contains both large (11” x 7.7”) and small (7.7
x 5.5”) base grids; you may use either size for this small circuit.
Build the circuit shown on the left by placing all the parts with a black 1 next to them
on the base grid first. Then, assemble parts marked with a 2. Install three (3) “AA”
batteries (not included) into the battery holder (B3) if you have not done so already.
Turn on the slide switch (S1), and enjoy the light show from the color LED (D8).
For best effects, dim the room lights.

Project 2
White Light
Modify the preceding circuit by replacing the color
LED (D8) with the white LED (D6), as shown. The
white LED is brighter, but does not change colors.
Modify the preceding circuit by replacing the white LED (D6) with
the horn (W1), as shown. This circuit makes noise instead of light.
Project 3
Horn
Snappy says when you turn on the slide switch,
electricity flows from the batteries, through the color
LED and back to the battery through the switch. If the
switch is off, the flow of electricity is blocked, and the
color LED won’t light.
LEDs are light emitting diodes, which convert electrical
energy into light. The color of the light depends on the
characteristics of the material used in them. The color
LED actually contains separate red, green, and blue
lights, with a micro-circuit controlling them.
NOTE: this circuit (and many others
in this book) have an LED being used
without a resistor or other component
to limit the electric current through it.
Normally this could damage an LED
but your Snap Circuits
®
LEDs include
internal protection resistors, and will
not be damaged. Be careful if you
later use other electrical sets with
unprotected LEDs.

The white LED produces
very bright light. LEDs like
this one are increasingly
being used for home
lighting and flashlights.
They are more efficient
than normal light bulbs.

Project 4 Simple Light Tunnel
Build the circuit shown on the left by placing all the parts with a black 1
next to them on the board first. Then, place parts marked with a 2. Install
three (3) “AA” batteries (not included) into the battery holder (B3) if you
have not done so already.
Turn on the slide switch (S1). The light tunnel (U30) puts on a show.
For best effects, dim the room lights. Try GENTLY pressing on the
center of the mirror in the light tunnel, and notice how the light patterns
bend inward a little.
The light tunnel has 3 red, 3 green, and
3 blue LEDs. There is a mirror behind
them, and a semi-transparent mirror
above them; the combination of these
produces the effects you see.

Place the lined lens attachment on the color LED
(D8) and turn the clear part so that the lines on it
converge towards the left, as shown. Turn on the
slide switch (S1) and place the circuit so that the
color LED is right next to a wall or box. The color
LED and lined lens make a display of light that
resembles a fireworks show. For best effects make
the room very dark.
Try rotating the lined lens and see how the light
display changes.

Project 7 Projector
Use two vertical snap wires (V1) and mount the white
LED (D6) on them so it will shine towards a wall, then
place the projector on the white LED.
Place the circuit in a dark room and point it towards a
wall, white walls give best effects. Turn on the slide
switch (S1) and adjust the knob on the projector to show
the 6 images on the wall. The room should be very dark
for best effects. You can also get good results by
projecting the images on a white box a few feet away.

These red pieces are the same vertical
snap wire (V1), mounted so it stands up.
Use the project 2 circuit, but place the
projector on the white LED (D6). Place the
circuit in a dark room, preferably with a flat
white ceiling. Turn on the slide switch (S1)
and adjust the knob on the projector to show
the 6 images on the ceiling. The room should
be very dark for best effects.

Use either of the two preceding circuits but
replace the white LED (D6) with the color LED
(D8). The color LED is not as bright as the white
LED, but the images look different for each color
produced by the color LED. The effects are best
seen in a very dark room.

Assembly (adult supervision recommended). Follow these assembly
instructions in order:
1. Place base grid supports on the base grid labeled A in the drawing.
2. Place parts on grid B, and install into base grid support on grid A.
3. Place parts on grid C (except the vertical snap wire (V1) that connects
to grid B, and the 2-snap wire that attaches to it), and install into base
grid supports on grid A. Finish connection of the V1 connecting
between grids B-C, add the 2-snap wire that attaches to it, and add
the stabilizer between grids B & C.
4. Install remaining parts on grid A.
5. Add the mirror and Q4 attachment.
Turn on the slide switch (S1). The light tunnel (U30) and color LED (D8) put
on a show. To trigger an alarm, align the mirror so light from the white LED
(D6) reaches the phototransistor (Q4); remove and re-install it in the spring if
needed. Try giving the mirror a push so it bounces back and forth on the spring.
You can swap the locations of the white and color LEDs (D6 & D8), but
in some cases the color LED may not activate the alarm.
