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, 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 the speaker, lamp, whistle chip, ICs

(which must be connected properly), motor, photoresistor, or

resistor.

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 ICs 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.

NEVER

touch the motor when it is spinning at high speed.

Note: If you have the more advanced Models SC-300, SC-500, or SC-750,

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.

Examples of SHORT CIRCUITS - NEVER DO THESE!!!

You are encouraged to tell us about new circuits you create. If they are

unique, we will post them with your name and state on our website at

www.snapcircuits.net/kidkreations.htm. Send your suggestions to

Elenco

provides a circuit designer so that you can make your own Snap

drawings. This Microsoft

Word document can be downloaded

from www.snapcircuits.net/SnapDesigner.doc or through the

WARNING: SHOCK HAZARD - Never connect Snap Circuits

the electrical outlets in your home in any way!

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.

NEVER

DO!

Warning to Snap Rover owners: Do not connect your parts to the

Rover body except when using our approved circuits, the Rover

body has a higher voltage which could damage your parts.

NEVER

DO!
