Manual Part 2

Assembly (adult supervision recommended):

1. Place base grid supports on base grid A & B.

2. Place parts on base grids C & D (leaving one end of the jumper

wires unconnected for now), and install into base grid supports

on grids A & B. The pegs should be facing inward on grid C and

outward on grid D.

3. Place parts on grid E, and install into the base grid support on

grid A, connecting to the vertical snap wire (V1) on grid C as you

do this.

4. Place remaining parts on grids A & B.

5. Connect a vertical snap wire (V1) between grids F & G, and

mount those grids at 45 degree angles and with pegs oriented

down on top of grids C & D using 6 stabilizers. Adjust the positions

of the stabilizers as needed.

6. Place the remaining parts on grid F, and connect to the blue

jumper wire on grid C.

7. Add the remaining jumper wires (1 blue, 1 black, and 1 red).

Set the meter to the 50mA scale and turn on the slide switch (S1).

The motor (M4) spins the fan and white LED (D6) lights; the meter

measures the current through them. The color LED (D8) is bright

if room is dark, and gets dim as you shine light on phototransistor

(Q4); shine a bright light on Q4 to turn off D8. Push the press

switch (S2) to hear a doorbell sound from the melody IC (32) and

light the lamp (L4). If desired, place the light covers with a slide on

any of the LEDs or the lamp.

The light covers and slides may be placed on the LEDs (D6 and

D8) or lamp (L4) as decoration. Fold the slides as indicated and

slide them into the slots on the cover, as shown.

Note: the 4-snap,

6-snap wires, the ber

optic festive tree and

its mounting base

(which may be laid on

the 6-snap wire so it

balances the festive

tree), are only included

as decoration and

are not necessary.
