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.

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 motor, melody IC, or LED (which has an
internal protection resistor), 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. 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 motor, melody IC, or an LED (which has an internal
protection resistor).
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.
NEVER connect to an electrical outlet in your home in any way.
NEVER leave a circuit unattended when it is turned on.
NEVER try to turn the shaft of the orange motor (M9) by hand or with tools, as
this may break it.
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 only be mounted overhead or on
walls with great care, as the vibrations they produce could cause them to fall.
The circuits in this set have been checked with the parts shown in them.
