Elenco Snap Circuits Motion - Manual (Page 26)

Build the circuit shown here. Mount the 1.75” gear
on the geared motor (GM) with the rubber rings to
keep it from sliding out of position, and place it on
the mini car frame. Place the switcher (S6) directly
on the geared motor, set S6 to the middle position,
place a battery holder (B1) on the front of the mini
car frame, connect the red jumper wire from + on
B1 to C on S6, then connect black wire from — on
B1 to B on S6. Be sure the jumper wires will not
interfere with the gears or wheels.
Set S6 to the “A” side to make the mini car go
forward, or set it to the “D” side to make the mini
car go backwards and turn. Be careful that the mini
car does not fall off a table or down a stairway!
Project 24 Mini Car with
On-Board Control
Add the color LED (D8) directly
on top of the jumper wire
connections to the battery holder
(B1, LED + to battery +).
Alternately, you can use the
red/yellow bicolor LED (D10),
oriented in either direction.
Remove the LED when you are
finished. Note that normally
connecting an LED directly to a
battery can damage the LED, but
the color LED has an internal
resistor that will protect it.

Mini Car
with Light
Mount the 1.75” gear on the geared motor (GM), with
the rubber rings to keep it from sliding out of position,
and place it on the mini car frame. Mount the
red/yellow bicolor LED (D10), vibration switch (S4),
and pivot stand to the geared motor in the
arrangement shown, and connect to the circuit on the
base grid using the red & black jumper wires as
shown.
Turn on the slide switch (S1), and then use the
switcher (S6) to make the mini car go forward,
backward-turn, or stop. When the mini car is moving,
vibrations will often light the red/yellow LED. You can
follow the mini car around the room or table carrying
the base grid while using S6 to control it. Be careful
to follow it closely so you don’t over-extend the
jumper wires, and to keep it from falling off the table.
