Variants
Use the preceding circuit, but
replace any of the LEDs (D9 &
D12) with the blink red LED
(D11), the lamp (L4), or the
melody IC (U32).

Manual Rotation Vertical Lights

Assembly (adult supervision recommended):
1. Place base grid supports on base grid A.
2. Place parts on grid B, and install into base grid support on grid A. The pegs should be facing inward.
3. Mount the blue & color2 and LEDs (D9 & D12) to the 3D snaps, and attach two 1-snap wires on
opposite sides, as shown.
4. Place the remaining parts on grid A.
5. Mount the LED assembly from step 3 between the vertical snap wire that hangs upside down from
grid B and the 3-snap wire on grid A, as shown. The "+" side of the LEDs should be up.
Turn on the slide switch (S1). The color2 and blue LEDs should light; rotate them to any desired
position.
Project 80

Stay with the Magnet

Build the circuit, mounting the gear insert
on the orange motor (M9) and placing the
compass so it is centered on the gear
insert. Turn on the slide switch (S1) and
hold the magnet near the side of the
compass. The compass needle should
always point towards the magnet, even as
the motor rotates the compass. Move the
magnet around until you find a position
where this works well. Next, move the
magnet far away. The compass needle
should point north, and continue pointing
north as the compass itself is rotated by the
motor.
