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 color2 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 color2 LED actually contains separate
red, green, and blue lights, with a micro-circuit
controlling them; the colors can be combined to
produce yellow, cyan, purple, and white.
Snap Circuits
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; be sure the
battery springs are compressed straight back, and not bent up, down, or to one side.
Turn on the slide switch (S1), and enjoy the light show from the color2 LED (D12). For
best effects, place one of the LED attachments (fiber optic festive tree or egg), and dim
the room lights. The fiber optic festive tree must be used with its mounting base.

Project 2
Modify the preceding circuit by replacing the color2
LED (D12) with the blue LED (D9), as shown. The
blue LED is brighter, but does not change colors.

Color Light

uses electronic blocks that snap onto a clear plastic base grid to build
®
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 festive tree and egg may also be used
with other Snap Circuits® LEDs from different sets.

Blue Light

Modify the preceding circuit by replacing
the blue LED (D9) with the blink red
LED (D11), as shown. The blink red
LED flashes about once a second.
