Data Sheet

Assembly (adult supervision recommended):
1. Place base grid supports and orange motor (M9) on base grid A.
Place the small gear on the gear insert and mount on the orange
motor. The teeth on the gear should face up.
2. Mount the blue & color2 LEDs (D9 & D12) to the 3D snaps, and
attach the large gear and a 1-snap wire, as shown. The teeth on the
gear should face the LEDs, and the “+” side of the LEDs should be
towards the gear.
3. Mount parts on grids B & C, and install in base grid supports in grid
A. The pegs should be facing inward.
4. Mount the LED assembly from step 2 between the 5-snap wire on
grid B and the 2-snap wire on grid C, as shown. The teeth on the large
and small gears should align.
5. Place remaining parts on grid A.
Turn on the slide switch (S1). The color2 and blue LEDs should light,
and be rotated by the gears.
Note: If the gears do not rotate properly, you may get better
performance if you spread the tops of the mini base grids apart. You
can do this by adding another base grid as a “roof” and securing with 4
stabilizers, as done in project 20.
