Elenco R/C Snap Rover&reg - Manual (Page 8)

-7-
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, motor, integrated circuit, 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
ICs using configurations given in the projects, incorrectly doing so may
damage them. Elenco
® Electronics 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, motor, horn, or the RX1
and U8 modules (which must be connected properly).
ALWAYS use the LED and 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 RX1 and U8 modules 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.
Note: If you have a more advanced model, there are additional
guidelines in your other project manual(s).
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.
WARNING: SHOCK HAZARD - Never connect Snap Circuits ® to
the electrical outlets in your home in any way!
Examples of SHORT•CIRCUITS - NEVER•DO•THESE!!!
You are encouraged to tell us about new circuits you create. Upon review,
we will post them with your name in a special section on our website. If
we use them in future manual revisions, we will send you a copy of the
manual so you can show your family and friends. Send your suggestions
to Elenco
® Electronics.
CAUTION: Do not mix alkaline, standard (carbon-zinc), or
rechargeable (nickel-cadmium) batteries.

DO’s and DON’Ts of Building Circuits
Placing a jumper
wire directly across
the battery snaps is
a SHORT CIRCUIT.
When the 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.

NEVER
DO!
Warning to Snap Circuits ® owners: Do not use parts from
other Snap Circuits ® sets with this kit except for the circuits
on page 22. The Snap Rover ® uses higher voltage which
could damage those parts. Our website www.snapcircuits.net
also has approved circuits that you can use.
