Before using your new Electronic Snap Circuits, please read this

place for future references.
DO’s AND DON’Ts OF BUILDING CIRCUITS
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, lamp, motor, integrate circuit, etc.), and
wiring paths between them and back. You must be careful not to create
“short circuits” as this will damage components and / or quickly drain
the batteries. Only connect the ICs using configurations given in the
projects, incorrectly doing so may damage them.
Steren is not responsible for parts damaged due to incorrect wiring.
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 the speaker, lamp, capacitors, motor,
microphone, etc.
Always disconnect the batteries immediately and check your wiring
if something appears to be getting hot.
Always check your wiring before turning on a circuit.
Never leave a circuit unattended when it is turned on.
Never touch the motor when it is spinning at high speed.

WARNING
SHOCK HAZARD
Never connect snap circuits to the electrical outlets in
your home in any way!
HOW TO USE THE PARTS
The snap circuit kit 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 indifferent colors and have numbers on them so that
you can easily identify them.
The circuit you will build is shown in color and 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.

ENGLISH
ENGLISH-04
This is a wire block which is blue and comes in different wire lengths.
To build each circuit, you have a power source block number that need
2 AA batteries (not included with the snap circuit kit).
A large clear plastic base grid is included with this kit to help keep the
circuit block together. You do not need this base to build your circuits,
but it does help in keeping your circuit together neatly.
The 2,5V bulb come packaged separate from their socket.
Some circuits use the jumper wires to make unusual connections
While building the projects, be careful not to accidentally make a
direct connection across the battery holder (a “short circuit”), as
this will damage and / or quickly drain the batteries.

PROJECTS
1.- Lamp
Turn the switch 15 on,
the lamp 18 will Light up.
Turn the switch off and the
lamp will power off.
2.- Magnet-controlled lamp
Place a magnet close to the
switch 13, the lamp 18 will
light up. Take the magnet
away from the switch 13,
the lamp 18 will power off.

ENGLISH
ENGLISH-09
3.- Electric fan
Place the yellow fan on the
motor, close the switch 15
and the fan will spin round.
4.- Magnet-controlled
electric fan
Place the yellow fan on the
motor, place a magnet close
to the switch 13, the fan will
spin round. Keep the
magnet away from the
switch 13 and the fan will
stop.

ENGLISH
ENGLISH-10
5.- Flying fan
Place the yellow fan on the
motor, press the switch 15,
when the motor reaches its
top speed, the fan will fly up
into air (Note: keep your
head out of the way!)
6.- Magnet-controlled flying
fan
Replace the switch 15 with a
switch 13, place a magnet
close to the switch 13, when
the motor reaches its top
speed, take the magnet
away from the switch and fan
will fly up into air (Note: keep
your head out of the way).

ENGLISH
ENGLISH-11
7.- Rotation of an electric
motor clockwise and
counterclockwise
Press the switch 15, you
will see the that the
rotation of the motor is
reversed, the fan won’t fly
up into the air, but
becomes in an air
conditioner fan.
8.- Electric fan and lamp connected in series
Place the yellow fan on the motor, close the switch 15, the fan will spin
round and the lamp will light up. Turn the switch off, the fan will stop and
the lamp 18 will power off.

ENGLISH
ENGLISH-12
9.- Electric fan and lamp connected in parallel
Place the yellow fan on the motor, close the switch 15, the fan will spin
round and the lamp 18 will light up. Turn the switch off, the fan will stop
and the lamp 18 will power off.
10.- Using a LED
The LED requires a resistor
connected un series to avoid
burning out, you can see this
in the underside of the LED.
Close the switch 15, the LED
17 will light up.

ENGLISH
ENGLISH-13
11.- Magnet-controlled LED
Place a magnet close to the
switch 13, the LED 17 will
light up, keep the magnet
away and the LED 17 will
power off.
12.- LED and electric fan connected in series
Close the switch 15, the LED 17 will light up, but the motor 24 won’t spin
round, this is due to the motor requires a bigger quantity of energy and it
is consumed by the LED.

ENGLISH
ENGLISH-14
13.- LED and lamp connected in parallel
Close the switch 15, the LED 17 and the lamp 18 will light up at the
same time, but the LED light will be dark, it is because the motor
requires bigger quantity of energy than the LED.
14.- LED and electric fan connected in parallel
Close the switch 15,m the LED 17 will light up and the fan will spin
round.

ENGLISH
ENGLISH-15
15.- One way conductivity of a LED
Close the switch 15, the LED 17 won’t light up, it is because the LED
only allows current from positive to negative and not from negative to
positive.
16.- Connecting a LED, lamp and electric motor in series
After assembled the circuit, only the LED 17 will light up, the lamp 18
and the motor 24 won’t work because of the low current.

ENGLISH
ENGLISH-16
17.- LED, lamp and electric motor connected in parallel
Close the switch 15, the LED 17 and the lamp 18 will light up at the
same time, the motor 24 will spin round.
18.- LED, lamp and electric motor connected in series-parallel
After assembled the circuit, the motor 24 will spin round, the LED 17
will light up, but the lamp 18 won’t, it is because the lamp and Led are
connected in series, and the current that pass through the lamp it is very
low. After the LED, the lamp and the motor are connected in parallel,
this is a series-parallel connection.

ENGLISH
ENGLISH-17
19.- LED, lamp and electric motor connected in series-parallel (2)
The lamp 18 and the LED 17 will light up but the motor 24 won’t.
20.- LED, lamp and electric motor connected in series – parallel (3)

ENGLISH
ENGLISH-19
23.- Electric fan and LED working by turns
Operation as last project
24.- Changeable-light lamp

round, if you put the magnet close to the switch 13 you can control the
rotation speed.
26.- Circuit tester
The tester can check if a wire has a break or not. Place the two ends
of the wire on A and B terminals, if the LED 17 lights up, the wire is not
damaged, but if not, the wire is broken.
