How to Use Snap Circuits

®

Snap Circuits

®

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, light blocks,
battery blocks, different length wire blocks, etc.
These blocks are different colors and have
numbers on them so that you can easily
identify them. The blocks you will be using are
shown as color symbols with level numbers
next to them, allowing you to easily snap them
together to form a circuit.

For Example:

This is the switch block which is green and has
the marking on it. The part symbols in this
booklet may not exactly match the appearance
of the actual parts, but will clearly identify them.

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.

You need a power source to build each circuit.
This is labeled and requires three (3) “AA”
batteries (not included).

A large clear plastic base grid is included with
this kit to help keep the circuit blocks properly
spaced. You will see evenly spaced posts that
the different blocks snap into. 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.
Some circuits use the jumper wires to make
unusual connections. Just clip them to the
metal snaps or as indicated.

Usually when the motor is used, the fan will
be placed on it.

No computer is needed for introductory
projects (some projects use the U21
microcontroller, but with a factory-loaded
program).

Occasionally you may feel static electricity if
you touch a circuit when the programming
cable is connected, usually when humidity is
very low. Don’t worry; this is harmless. It occurs
because the cable makes an easy electrical
path between your body and the ground,
allowing static that has built up on you to
dissipate. Sometimes this static electricity may
reset the microcontroller (U21), causing it to
re-start its program.

Note: While building the projects, be careful
not to accidentally make a direct connection
across the battery holder (a “short circuit”),
as this may damage and/or quickly drain the
batteries.
