Parts
(Part designs are subject to change without notice).
BASE GRID
The blue snap wires are wires
used to connect components.
They are used to transport
electricity and do not affect circuit
performance. They come in different
lengths to allow orderly arrangement of
connections on the base grid.
The white jumper wire makes
flexible connections for times
when using the snap wires
would be difficult.
The red snap-to-pin wire
allows for direct connection to
the Arduino UNO circuit board.
Wires transport electricity just
like pipes are used to
transport water. The colorful plastic coating
protects them and prevents electricity from
getting in or out.
BATTERY HOLDER
The base grid is a platform for mounting parts
and wires. It functions like the printed circuit
boards used in most electronic products, or like
how the walls are used for
mounting the electrical wiring in
your home.
SNAP WIRES & JUMPER WIRES
Batteries, like that in your 9V battery connector,
produce an electrical voltage using a chemical
reaction. This “voltage” can be thought of as
electrical pressure pushing electricity through a
circuit just like a pump pushes water through
pipes. This voltage is much lower and much safer
than that used in your house wiring. Using more
batteries increases the “pressure”, therefore,
more electricity flows. Snapino
TM
circuits can also
be powered through the USB.
Battery Holder
SWITCHES
The press switch (S2) and the switch in the 9V
battery holder connect (pressed or “ON”) or
disconnect (not pressed or “OFF”) the wires in a
circuit. When ON they have no effect on circuit
performance. Switches turn on electricity just like
a faucet turns on water from a pipe.
LEDs
The red & green LEDs (D1 & D2) are light
emitting diodes, and may be thought of as a
special one-way light bulb. In the “forward”
direction, (indicated by the “arrow” in the symbol)
electricity flows if the voltage exceeds a turn-on
threshold (about 1.5V for red and yellow, about
2.0V for green, and about 3.0V for blue;
brightness then increases. A high current will
burn out an LED, so your Snap Circuits
®
LEDs
have internal resistors to protect them. LEDs
block electricity in the “reverse” direction.
Red & green LEDs (D1 & D2)
Red / yellow LED (D10)
The red/yellow LED (D10) is like the others but
has red and yellow LEDs connected in opposite
directions.
