Green Dot
Place the parts on the base grid, then assemble the
parts on the two 45 degree vertical snap wires (V2).
Turn on the slide switch (S1); the LEDs light as the
melody IC (U32) makes a strange sound; the sound
may not be very loud. The blue LED (D9) next to the
motor (M4) creates a green line across the spinning
fan.
Remove the clear motor (M4). Now the sound is much
louder.
2-Sided Grid
Assembly:
1. Place base grid supports on base grid A.
2. Place the parts (except for attachments on the
motors) on grid B, and install into base grid
supports on grid A.
3. Mount the gear insert and the large gear on the
orange motor (M9), teeth facing out.
4. Attach the fan to the clear motor (M4).
5. Place the remaining parts on grid A.
This circuit demonstrates using the 2-sided base
grid. Turn on the slide switch (S1); the lights and
motors all turn on.
