TRANSISTORS
The phototransistor (Q4) is a transistor that
uses light to control electric current.

The color organ (U22) contains resistors, capacitors,
transistors, a tri-color LED, and integrated circuits. The
LED in it can change colors by direct control, or in synch
with an audio input signal. A schematic for it is available at
www.snapcircuits.net/faq.

The strobe IC (U23) contains resistors, capacitors, and
transistors that are needed to make a strobe light circuit.
A schematic for it is available at www.snapcircuits.net/faq.

OTHER PARTS
The stereo cable is used to connect
your music device to the color organ
(U22).
Prismatic film separates light into
different colors. The red, green, & blue
filters filter out colors.
The disc holder and discs produce amazing effects when
used with the Strobe Effects circuit (project 46).
The Infrared module (U24) is a miniaturized
infrared receiver circuit for remote control.
The PNP & NPN transistors (Q1 & Q2) are
components that use a small electric current to
control a large current, and are used in switching,
amplifier, and buffering applications. They are
easy to miniaturize, and are the main building
blocks of integrated circuits including the
microprocessor and memory circuits in
computers.
PNP & NPN Transistors (Q1 & Q2)
The LED attachments can be used with
any of the LEDs (red, white, color, and
the color organ) to enhance the light
effects.
The fiber optic cable carries light
between two places. The light can be
encoded to transmit information. The
clear and black holders are used to
attach it to circuits.
