The Electronic Snap Circuit Kit has 204 projects. They are simple to build and
understand.
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 in different 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.
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.
To build each circuit, you will have two (2) power source blocks marked
that need two (2) “AA” batteries each (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 will see evenly spaced posts that the different blocks snap
into. You do not need this base to build your circuits, but it does help in
keeping your circuit together neatly. The base has rows labeled A-G and
columns labeled 1-10.
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.
The 2.5V bulb comes packaged separate from its socket. Install the bulb in
the lamp socket whenever that part is used. Do the same for the 6V bulb
and socket .
Place the fan on the motor whenever that part is used, unless the project
you are building says not to use it.
Some circuits use the jumper wires to make unusual connections. Just clip
them to the metal snaps or as indicated.
Note: 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.
CreatingYour Own 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) 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.
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.
You are encouraged to tell us about new circuits you create. Upon review, we
will post them with your name, age, and hometown in a special section on our
website.
Troubleshooting
Most circuit problems are due to incorrect assembly, always double-check that
your circuit exactly matches the drawing for it. Be sure that parts with
positive/negative markings are positioned as per the drawing. Sometimes the
light bulbs come loose, tighten them as needed. Try replacing the batteries.
