Project 1
Color Light
Snap Circuits
®
uses electronic blocks that snap onto a clear plastic base grid to
build different circuits. These blocks have different colors and numbers on them so
you can easily identify them. This set contains both large (11” x 7.7”) and small (7.7”
x 5.5”) base grids; you may use either size for this small circuit.
Build the circuit shown on the left by placing all the parts with a black 1 next to them
on the base grid first. Then, assemble parts marked with a 2. Install three (3) “AA”
batteries (not included) into the battery holder (B3) if you have not done so already.
Turn on the slide switch (S1), and enjoy the light show from the color LED (D8).
For best effects, dim the room lights.

Project 2
White Light
Modify the preceding circuit by replacing the color
LED (D8) with the white LED (D6), as shown. The
white LED is brighter, but does not change colors.
Modify the preceding circuit by replacing the white LED (D6) with
the horn (W1), as shown. This circuit makes noise instead of light.
Project 3
Horn
Snappy says when you turn on the slide switch,
electricity flows from the batteries, through the color
LED and back to the battery through the switch. If the
switch is off, the flow of electricity is blocked, and the
color LED won’t light.
LEDs are light emitting diodes, which convert electrical
energy into light. The color of the light depends on the
characteristics of the material used in them. The color
LED actually contains separate red, green, and blue
lights, with a micro-circuit controlling them.
NOTE: this circuit (and many others
in this book) have an LED being used
without a resistor or other component
to limit the electric current through it.
Normally this could damage an LED
but your Snap Circuits
®
LEDs include
internal protection resistors, and will
not be damaged. Be careful if you
later use other electrical sets with
unprotected LEDs.

The white LED produces
very bright light. LEDs like
this one are increasingly
being used for home
lighting and flashlights.
They are more efficient
than normal light bulbs.
