How to Use Circuit Maker Sound Plus 200

Circuit Maker Sound Plus 200 uses building

blocks with snaps to build the different

electrical and electronic circuits in the projects.

Each block has a function: there are switch

blocks, light blocks, battery blocks, different

length wire blocks, etc. These blocks are

different colors and have numbers on them so

that you can easily identify them. The blocks

you will be using are shown as color symbols

with level numbers next to them, allowing you

to easily snap them together to form a circuit.

For Example:

This is the switch block which is green and has

the marking on it. The part symbols in this

booklet may not exactly match the appearance

of the actual parts, but will clearly identify them.

This is a wire block which is blue and comes

in different wire lengths.

This one has the number , , , ,

or on it depending on the length of the wire

connection required.

There is also a 1-snap wire that is used as a

spacer or for interconnection between different

layers.

You need a power source to build each circuit.

This is labeled and requires three (3) 1.5V

“AA” batteries (not included).

A large clear plastic base grid is included with

this kit to help keep the circuit blocks properly

spaced. You will see evenly spaced posts that

the different blocks snap into. The base has

rows labeled A-G and columns labeled 1-10.

Next to each part in every circuit drawing is a

small number in black. This tells you which

level the component is placed at. Place all

parts on level 1 first, then all of the parts on

level 2, then all of the parts on level 3, etc.

Some circuits use the jumper wires to make

unusual connections. Just clip them to the

metal snaps or as indicated.

Note: While building the projects, be careful

not to accidentally make a direct connection

across the battery holder (a “short circuit”),

as this may damage and/or quickly drain the

batteries.

About Your Circuit Maker Sound Plus 200 Parts

RESISTORS

The photoresistor (RP) is a light-sensitive resistor, its

value changes from nearly infinite in total darkness to

about 1,000W when a bright light shines on it.

Resistors “resist” the flow of electricity and are used to

control or limit the current in a circuit. Circuit Maker Skill

Builder 125 includes 100W (R1), 1kW (R2), 5.1kW (R3),

and 100kW (R5) resistors (“k” symbolizes 1,000, so

R3 is really 5,100W). Materials like metal have very low

resistance (<1W), while materials like paper, plastic,

and air have near-infinite resistance. Increasing circuit

resistance reduces the flow of electricity.

Resistors (R1, R2, R3, & R5)

(Part designs are subject to change without notice).

BASE GRID

The blue snap wires

are wires used to

connect components.

They are used to transport

electricity and do not affect

circuit performance. They come in

different lengths to allow orderly

arrangement of connections on the base grid.

The red and black

jumper wires make

flexible connections

for times when using

the snap wires would be difficult.

They also are used to make

connections off the base grid.

Wires transport electricity just like pipes are used to

transport water. The colorful plastic coating protects

them and prevents electricity from getting in or out.

BATTERY HOLDER

The base grid is a platform for mounting parts and

wires. It functions like the printed circuit boards used

in most electronic products, or like how the walls are

used for mounting the electrical wiring in your home.

SNAP WIRES & JUMPER WIRES

The batteries (B3) produce an electrical voltage using

a chemical reaction. This “voltage” can be thought of

as electrical pressure, pushing electricity through a

circuit just like a pump pushes water through pipes.

This voltage is much lower and much safer than that

used in your house wiring. Using more batteries

increases the “pressure”, therefore, more electricity

flows.

Battery Holder (B3)

SLIDE & PRESS SWITCHES

The slide and press switches (S1 & S2) connect

(pressed or “ON”) or disconnect (not pressed or

“OFF”) the wires in a circuit. When ON they have no

effect on circuit performance. Switches turn on

electricity just like a faucet turns on water from a pipe.

Slide & Press Switches (S1 & S2)

The adjustable resistor (RV) is

a 50kW resistor but with

a center tap that can

be adjusted between

200W and 50kW.

About Your Circuit Maker Sound Plus 200 Parts

SPEAKER

WHISTLE CHIP

The whistle chip (WC) contains two thin plates. When

an electrical signal is applied across them they will

stretch slightly in an effort to separate (like two

magnets opposing each other), when the signal is

removed they come back together. If the electrical

signal applied across them is changing quickly, then

the plates will vibrate. These vibrations create

variations in air

pressure that

your ears feel

just like sound

from a speaker.

Space War IC:

Some types of electronic components can be super-

miniaturized, allowing many thousands of parts to fit into an

area smaller that your fingernail. These “integrated circuits”

(ICs) are used in everything from simple electronic toys to the

most advanced computers. The space war and recording IC

modules (U3 & U6) in Circuit Maker Sound Plus 200 are

actually modules containing specialized sound-generation ICs

and other supporting components (resistors, capacitors, and

transistors) that are always needed with them. This was done

to simplify the connections you need to make to use them.

The descriptions for these modules are given here for those

interested; see the projects for connection examples:

Connections:

(+) - power from batteries

(–) - power return to batteries

OUT - output connection

IN1, IN2 - control inputs

Connect each control input to

(–) power to sequence

through 8 sounds.

Recording IC Module:

Connections:

(+) - power from batteries

(–) - power return to batteries

RC - record

Play - play

OUT - output connection

Mic + - microphone input

Mic – - microphone input

See Project #4 for example of

proper connections.

The speaker (SP2) converts

electricity into sound by making

mechanical vibrations. These

vibrations create variations

in air pressure, which travel

across the room. You “hear”

sound when your ears feel

these air pressure vari-

ations.

CAPACITORS

Capacitors are components that can store electrical

pressure (voltage) for periods of time, higher values

have more storage. Because of this storage ability

they block unchanging voltage signals and pass fast

changing voltages. Capacitors are used for filtering

and oscillation circuits. This kit includes 0.1mF (C2),

10mF (C3), and 100mF (C4) capacitors. The whistle

chip (WC) also acts like a 0.02mF capacitor in addition

to its sound

properties.

Microphone

(X1)

The microphone (X1) is actually a resistor that

changes in value when changes in air pressure

(sounds) apply pressure to its surface.

MICROPHONE

LAMP

A light bulb, such as in the 4.5V lamp (L4), contains a

special thin high-resistance wire. When a lot of

electricity flows through, this wire gets so hot it glows

bright. Voltages above the bulb’s rating can burn out

the wire.

Lamp (L4)

Speaker (SP2)

LED

The red LED (D1) is a light emitting diode and may be

thought of as a special one-way light bulb. In the

“forward” direction, (indicated by the “arrow” in the

symbol) electricity flows if the voltage exceeds a turn-

on threshold (about 1.5V); brightness then increases.

A high current will burn out an LED, so the current

must be limited by

other components in

the circuit. LEDs

block electricity in the

“reverse” direction.

TRANSISTORS

The PNP transistor (Q1) and NPN transistor (Q2)

are components that use a small electric current to

control a large current, and is used in switching,

amplifier, and buffering applications. Transistors are

easy to miniaturize, and are the main building blocks

of integrated circuits including the microprocessor and

memory circuits in computers.

Introduction to Electricity

What is electricity? Nobody really knows. We only know how to produce it,

understand its properties, and how to control it. Electricity is the movement of sub-

atomic charged particles (called electrons) through a material due to electrical

pressure across the material, such as from a battery.

Power sources, such as batteries, push electricity through a circuit, like a pump

pushes water through pipes. Wires carry electricity, like pipes carry water. Devices

like LEDs, motors, and speakers use the energy in electricity to do things. Switches

and transistors control the flow of electricity like valves and faucets control water.

Resistors limit the flow of electricity.

The electrical pressure exerted by a battery or other power source is called

voltage and is measured in volts (V). Notice the “+” and “–” signs on the battery;

these indicate which direction the battery will “pump” the electricity.

The electric current is a measure of how fast electricity is flowing in a wire, just

as the water current describes how fast water is flowing in a pipe. It is expressed

in amperes (A) or milliamps (mA, 1/1,000 of an ampere).

The “power” of electricity is a measure of how fast energy is moving through a

wire. It is a combination of the voltage and current (Power = Voltage x Current). It

is expressed in watts (W).

The resistance of a component or circuit represents how much it resists the

electrical pressure (voltage) and limits the flow of electric current. The relationship

is Voltage = Current x Resistance. When the resistance increases, less current

flows. Resistance is measured in ohms (W), or kilo ohms (kW, 1,000 ohms).

Nearly all of the electricity used in our world is produced at enormous generators

driven by steam or water pressure. Wires are used to efficiently transport this

energy to homes and businesses where it is used. Motors convert the electricity

back into mechanical form to drive machinery and appliances. The most important

aspect of electricity in our society is that it allows energy to be easily transported

over distances.

Note that “distances” includes not just large distances but also tiny distances. Try

to imagine a plumbing structure of the same complexity as the circuitry inside a

portable radio - it would have to be large because we can’t make water pipes so

small. Electricity allows complex designs to be made very small.

There are two ways of arranging parts in a circuit, in series or

in parallel. Here are examples:

Placing components in series increases the resistance; highest

value dominates. Placing components in parallel decreases the

resistance; lowest value dominates.

The parts within these series and parallel sub-circuits may be

arranged in different ways without changing what the circuit

does. Large circuits are made of combinations of smaller series

and parallel circuits.

DOs and DON’Ts of Building Circuits

After building the circuits given in this booklet, you may wish to experiment on

your own. Use the projects in this booklet as a guide, as many important design

concepts are introduced throughout them. Every circuit will include a power

source (the batteries), a resistance (which might be a resistor, capacitor, speaker,

integrated circuit, etc.), and wiring paths between them and back. You must be

careful not to create “short circuits” (very low-resistance paths across the

batteries, see examples at right) as this will damage components

and/or quickly

drain your batteries. Only connect the ICs using configurations given in the

projects, incorrectly doing so may damage them. ELENCO

is not responsible

for parts damaged due to incorrect wiring.

Here are some important guidelines:

ALWAYS USE EYE PROTECTION WHEN EXPERIMENTING ON YOUR

OWN.

ALWAYS include at least one component that will limit the current through a

circuit, such as the speaker, lamp, ICs (which must be connected

properly), motor, photoresistor, or resistor.

ALWAYS use the LED, NPN transistor, and switches in conjunction with other

components that will limit the current through them. Failure to do so

will create a short circuit and/or damage those parts.

ALWAYS disconnect your batteries immediately and check your wiring if

something appears to be getting hot.

ALWAYS check your wiring before turning on a circuit.

ALWAYS connect capacitors so that the “+” side gets the higher voltage.

ALWAYS connect ICs using configurations given in the projects or as per the

connection descriptions for the parts.

NEVER connect to an electrical outlet in your home in any way.

NEVER leave a circuit unattended when it is turned on.

NEVER touch the motor when it is spinning at high speed.

For all of the projects given in this book, the parts may be arranged in different

ways without changing the circuit. For example, the order of parts connected in

series or in parallel does not matter — what matters is how combinations of these

sub-circuits are arranged together.

Placing a 3-snap wire directly

across the batteries is a

SHORT CIRCUIT.

When the slide switch (S1) is turned on, this large circuit has a SHORT

CIRCUIT path (as shown by the arrows). The short circuit prevents any

other portions of the circuit from ever working.

NEVER

DO!

Examples of SHORT CIRCUITS - NEVER DO THESE!!!

Warning to Circuit Maker owners: Do not connect

additional voltage sources from other sets, or you

may damage your parts. Contact ELENCO

if you

have questions or need guidance.

WARNING: SHOCK HAZARD -

Never connect Circuit Maker

Sound Plus 200 to the electrical outlets in your home in any way!

ELENCO

is not responsible for parts

damaged due to incorrect wiring.

If you suspect you have damaged parts, you

can follow this procedure to systematically

determine which ones need replacing:

Note: Some of these tests connect an LED directly

across the batteries without another component

to limit the current. Normally this might damage

the LED, however, Circuit Maker LEDs have

internal resistors added to protect them from

incorrect wiring, and will not be damaged.

1. Red LED (D1), 4.5V lamp (L4), speaker

(SP2), and battery holder (B3): Place

batteries in holder. Place the red LED

directly across the battery holder (LED + to

battery +); it should light. Place the 4.5V

lamp directly across the battery holder, it

should light. “Tap” the speaker across the

battery holder contacts, you should hear

static as it touches. If none work, then

replace your batteries and repeat. If still bad,

then the battery holder is damaged.

2. Jumper wires: Use this mini-circuit to test

each jumper wire, the lamp should light.

3. Snap wires: Use this mini-circuit to test

each of the snap wires, one at a time. The

lamp should light.

4. Slide switch (S1) and press switch (S2):

Build Project #1; if the lamp (L4) doesn’t light

then the slide switch is bad. Replace the

slide switch with the press switch to test it.

100W (R1), 1KW (R2), and 5.1KW (R3)

resistors:

Build Project #10; the red LED

should be bright. If not, then R1 is damaged.

Next use the 1KW and 5.1KW resistors in

place of the 100W resistor; the LED should

be dimmer but still light.

6. Microphone (X1) and photoresistor (RP):

Build Project #13; if blowing into the

microphone does not change the LED (D1)

brightness then the microphone is bad.

Replace the microphone with the

photoresistor. Waving your hand over the

photoresistor (changing the light that shines

on it) should change the brightness of the

LED or the photoresistor is bad.

7. NPN transistor (Q2): Build the mini-circuit

shown here. The LED (D1) should only be

on if the press switch (S2) is pressed. If

otherwise, then the NPN is damaged.

8. PNP transistor (Q1): Build the mini-circuit

shown here. The LED (D1) should only be

on if the press switch (S2) is pressed. If

otherwise, then the PNP is damaged.

9. Adjustable resistor (RV): Build Project

#14, the resistor control lever can turn the

LED (D1) on and off.

10. Recording IC (U6): Build Project #4.

Make an 8 second recording, then listen to

the three pre-recorded songs.

11. Space war IC (U3: Build Project #2, both

switches (S1 and S2) should change the

sound.

12. Whistle chip (WC): Build Project #165.

When you press the press switch (S2) you

should hear sound.

13. 100KW resistor (R5), 0.1mF (C2)

capacitor and 10mF capacitor (C3):

Build Project #120, it makes sound unless

the resistor is bad. Place the 0.1mF

capacitor on top of the whistle chip (WC)

and the sound changes (pitch is lower).

Replace the 0.1mF with the 10mF (“+” on

left) and the circuit will “click” about once

a second.

14.

100mF (C4) capacitors: Build Project #75,

press the press switch (S2) and turn on the

slide switch (S1). The LED (D1) should be

lit for about 5 seconds then go out (press

the press switch again to reset this).

Project #1

Electric Light & Switch

Circuit Maker Sound Plus 200 uses electronic blocks that snap onto a

clear plastic grid to build different circuits. These blocks have different

colors and numbers on them so that you can easily identify them.

Build the circuit shown on the left by placing all the parts with a black 1

next to them on the board first. Then, assemble parts marked with a 2.

Install three (3) “AA” batteries (not included) into the battery holder (B3).

Turn on the slide switch (S1); the lamp (L4) lights.

Project #2

Build the circuit shown on the left, which uses the space war integrated

circuit (U3). Activate it by flipping the slide switch (S1) or pressing the

press switch (S2); do both several times and in combination. You will

hear an exciting range of sounds, as if a space war is raging!

Space War

Placement Level

Numbers

Like the other integrated circuits, the space war

IC is a super-miniaturized electronic circuit that

can play a variety of cool sounds stored in it by

using just a few extra components.

In movie studios, technicians are paid to insert

these sounds at the precise instant a gun is fired.

Try making your sound occur at the same time an

object hits the floor. It is not as easy as it sounds.

Placement

Level

Numbers

When you close the slide switch (S1), current

flows from the batteries through the lamp and

back to the battery through the switch. The closed

switch completes the circuit. In electronics this is

called a closed circuit. When the switch is opened,

the current can no longer flow back to the battery,

so the lamp goes out. In electronics this is called

an open circuit.

Project #10 Light Emitting Diode

Project #11

Dim Light

Use the circuit from Project #10, but replace the 100W resistor (R1) with the

1KW resistor (R2). The LED is not as bright now because the resistance is

higher. Now replace the 1KW resistor (R2) with the 5.1KW resistor (R3). The

LED is even dimmer now because the resistance is even higher.

LEDs use very little power and last

for thousands of hours. That’s why

they replaced the standard light bulb

in many products today.

Build the circuit shown on the left by placing all the parts with a black 1

next to them on the board first. Then, assemble parts marked with a 2.

When you close the slide switch (S1), current flows from the batteries

through the switch, through the resistor, through the LED (light emitting

diode) and back to the battery. The closed switch completes the circuit.

The resistor limits the current and prevents damage to the LED. NEVER

PLACE AN LED DIRECTLY ACROSS THE BATTERY! If no resistor is

in the circuit, the battery may push enough current through the LED to

damage the semiconductor that is used to produce the light. LEDs are

used in all types of electronic equipment to indicate conditions and pass

information to the user of that equipment.

Reverse the position of the LED (so the “+” is on the right) and turn on

the circuit - nothing happens. Since the LED is in backwards, current

cannot flow. The LED is like a check valve that lets current flow in only

one direction. Return the LED to the original position in the diagram.

Can you think of something you use every day that has an LED in it?

Use the circuit from Project #10, but replace the 5.1KW resistor (R3) with

the photoresistor (RP). Vary the brightness of the LED by adjusting how

much light shines on the photoresistor.

The photoresistor changes its resistance depending on how much light

shines on it.

Project #15

Build the circuit, but leave the ends of the

red and black jumper wires unconnected at

first.

When you place a paper clip (not included)

across the loose ends of the jumper wires

as shown, current flows from the batteries

through the resistor, through the LED, and

back to the battery. The paper clip

completes the circuit and current flows

through the LED. Place your fingers across

the terminals and the LED does not light.

Your body is too high of a resistance to

allow enough current to flow to light the

LED. If the voltage, which is electrical

pressure, was higher, current could be

pushed through your fingers and the LED

would light. This detector can be used to

see if materials like plastic, wood, cloth,

aluminum, or paper are a good conductor

or a poor conductor.

Adjustable Brightness

Project #13

Microphone Control

In this circuit, blowing on the microphone (X1) changes

the LED (D1) brightness.

The resistance of the microphone changes when you

blow on it. You can replace the microphone with one of

the resistors to see what resistor value it is closest to.

Project #14

Conduction Detector

Resistors are used to control or limit the flow of

electricity in a circuit. Higher resistor values reduce the

flow of electricity in a circuit.

In this circuit, the adjustable resistor is used to adjust

the LED brightness, to limit the current so the batteries

last longer, and to protect the LED from being damaged

by the batteries.

What is Resistance? Take your hands and rub them

together very fast. Your hands should feel warm. The

friction between your hands converts your effort into

heat. Resistance is the electrical friction between an

electric current and the material it is flowing through.

The adjustable resistor can be set for as low as 200W,

or as high as 50,000W (50kW).

In this circuit, changing the adjustable

resistor (RV) setting changes the

brightness of the LED (D1).

The lever on RV adjusts how much

resistive material the electric current

flows through.

Current Controllers

Build the circuit and turn on the

slide switch (S1), the LED (D1) will

be lit. To increase the LED

brightness, turn on the press switch

(S2). To decrease the LED

brightness, turn off the slide switch.

Project #18

Touch Light

Project #19

Speaker Static

Tap on the whistle chip and

the LED flickers. Tap again

and the LED may flicker for

a longer time. See how long

the LED will stay on.

Turn the slide switch (S1) on and

off several times. You hear static

from the speaker (SP2) when

you first turn on the switch, but

hear nothing after it is left on.

Turn on the circuit using the

slide switch (S1) and/or the

press switch (S2) and move

the adjustable resistor’s (RV)

control lever around to adjust

the brightness of the D1 and

L4. When the adjustable

resistor is set to one side,

that side will have low

resistance and its light turns

(assuming the switch on that

side is ON) on while the

other is OFF.

The speaker uses electromagnetism to create changes

in air pressure, which your ears feel and interpret as

sound. Think of the speaker as creating pressure waves

in the air just like waves in a pool. You only see waves

in the pool when you disturb the water, so the speaker

only makes sound when the voltage changes.

With the slide switch on, the 1KW

resistor (R2) controls the current.

Turning on the press switch places the

100W resistor (R1) in parallel with it to

decrease the total circuit resistance.

Turning off the slide switch places the

5.1KW resistor (R3) in series with

R1/R2 to increase the total resistance.

Project #22 Capacitors in Series

Project #23 Capacitors in Parallel

Turn on the slide switch (S1), then press and release the press switch (S2). The

LED (D1) becomes bright when the 100mF capacitor (C4) charges up with the press

switch on, then the LED slowly gets dim after you release the press switch.

Now turn off the slide switch. Repeat the test with the slide switch off; you’ll notice

the LED goes out much faster after you release the press switch. The much smaller

10mF capacitor (C3) is now in series with the 100mF and so reduces the total

capacitance (electrical storage capacity), and they discharge much faster. (Note

that this is opposite to how resistors in series work).

Turn off the slide switch (S1), then press and release the press switch (S2). The
