Door Bell Lights

Use the preceding circuit, but place one
of the LED attachments (fiber optic
festive tree or egg) on the color2 LED
(D12), and dim the room lights. The fiber
optic festive tree must be used with its
mounting base.
Project 104

Fan Speed

Use the project 102 circuit, but replace
the lamp (L4) with the clear motor (M4)
and fan. Turn the slide switch (S1) on;
the blue lights and the fan spins slowly.
When the reed switch closes U32, D12
and L4 turn on and the fan speeds up.

Door Bell

Build the circuit; mounting the gear insert and the
small gear on the orange motor (M9) as shown.
Place the magnet on the gear. Turn the slide switch
(S1) on; the gear rotates and the blue LED (D9)
lights. When the magnet moves near the reed
switch (S9), the melody IC (U32), color2 LED
(D12), and lamp (L4) turn on and off twice. The
melody IC sounds like a door bell.
Project 105

Disco Ball Switch

Use the project 102 circuit, but replace the
melody IC (U32) with the blink red LED
(D11) and remove the lamp (L4). Place the
egg on the blink red LED and the fiber optic
festive tree on the color2 LED (D12) using
the mounting base. Turn on the slide
switch; now the egg and tree light together.
