OBJECTIVE: Build an electronic game for racing.
Race Game
Project #58
OBJECTIVE: To show that motors and lamps may sometimes be
used as ordinary conductors.
Turn on the slide switch (S1) and press the press switch (S2), you hear
a machine gun sound (with music in the background). Thoroughly
cover the photoresistor (RP) with your hand and the sound becomes
a siren. After a while the sound will stop. Press the press switch and
it resumes.
Note that the LED (D1) lights, but the lamp (L2) does not light, and the
motor (M1) does not spin. Electricity is flowing through the lamp and
motor, but not enough to turn them on. So in this circuit they are acting
like 3-snap wires.
Using Parts as
Conductors
!
WARNING: Moving
parts. Do not touch
the fan or motor during
operation.
Cut this shape from page 128 in this
manual and tape it to the speaker.
Modify project #56 by adding the pointer as shown on the left. The paper
should be cut from page 128 and taped high enough on the speaker (SP) so
the pointer will stick over the fan with paper. Bend the pointer at a right angle
as shown on the left.
Setup: Cut out the grid with four (4) colors from page 128 and place it under
the base as shown on the left. Each player picks a color (or two colors if only
2 people are playing) and places a single snap on row G. The purple player
in column 1, the blue player in column 2, the green player in column 3, and the
yellow player in column 4. Spin the wheel by pressing the press switch (S2).
The first single color wedge that the pointer points to is the first player to start.
The Play: Each player gets a turn to press the press switch. They release the
press switch, and when the pointer points to a wedge, the players that match
the colors on the wedge get to move up one space. If a liner comes up like
the one shown on the left, then the players on each side of the line get to move
up two (2) spaces. The first player to reach the top row (A) wins. If two players
reach the top row at the same time, they must both drop down to row “D” and
play continues.
