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,
& will not be damaged. Be careful if you later use
other electrical sets with unprotected LEDs. T he
festive tree and egg may also be used with other
Snap Circuits
®
LEDs from dierent sets.
Snap Circuits
®
uses electronic blocks that snap onto
pegs to build dierent circuits. These blocks have
dierent colors and numbers on them so you can easily
identify them.
Place 4 bric2snap adapters and one 2x2 plate on the
baseplate as shown. Then mount the 3-snap wire and
battery holder (B3) on the adapters. Next, place the slide
switch (S1) and color LED (D8) on the other parts, as
shown. 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.
