Project 4 Simple Light Tunnel
Build the circuit shown on the left by placing all the parts with a black 1
next to them on the board first. Then, place parts marked with a 2. Install
three (3) “AA” batteries (not included) into the battery holder (B3) if you
have not done so already.
Turn on the slide switch (S1). The light tunnel (U30) puts on a show.
For best effects, dim the room lights. Try GENTLY pressing on the
center of the mirror in the light tunnel, and notice how the light patterns
bend inward a little.
The light tunnel has 3 red, 3 green, and
3 blue LEDs. There is a mirror behind
them, and a semi-transparent mirror
above them; the combination of these
produces the effects you see.

Project 5 Fireworks
Place the lined lens attachment on the color LED
(D8) and turn the clear part so that the lines on it
converge towards the left, as shown. Turn on the
slide switch (S1) and place the circuit so that the
color LED is right next to a wall or box. The color
LED and lined lens make a display of light that
resembles a fireworks show. For best effects make
the room very dark.
Try rotating the lined lens and see how the light
display changes.
