The document discusses breadboards, tools essential for building and testing temporary electronic circuits, highlighting their history, functionality, and components. It explains how modern breadboards, originating from wooden cutting boards, allow for the easy assembly and modification of circuits without soldering, and introduces key components like power supplies and jumper wires. Additionally, it emphasizes the importance of understanding breadboarding for IT students in hardware prototyping, collaboration with engineers, and the integration of hardware and software.

BREADBOARD CIRCUITS

2. BREADBOARD
• sometimes called a plugblock is used for
building temporary circuits. It is useful to
designers because it allows components to be
removed and replaced easily. It is useful to the
person who wants to build a circuit to
demonstrate its action, then to reuse the
components in another circuit.
This final Quarter, we will be focusing on
understanding what breadboard and its
components are, practically use breadboard to
see its potential as an IT student.

HISTORY OF BREADBOARD

4. HISTORY
Breadboards have a captivating history that dates
back to the early days of electronics. The name
“breadboard” originated from a time when people
would actually use wooden bread cutting boards
to build their electronic circuits. They would place
components like resistors, capacitors, and
transistors on the wooden surface and connect
them with wires.

6. HISTORY
The modern breadboard, made of plastic and
metal, was invented in the 1960s. It was designed
to provide a reusable platform for rapid
prototyping and testing of electronic circuits.
Since then, breadboards have become an
essential tool for electronics hobbyists, students,
and professionals.

HOW BREADBOARD
WORKS

9. HOW IT WORK?
Breadboards are rectangular boards featuring a grid of
small holes. Beneath the surface, metal strips connect
these holes in a specific pattern, allowing components
to be electrically connected without the need for
soldering. The holes are typically spaced 0.1 inches
apart, which is the standard spacing for most electronic
components.
To create a circuit, simply insert the leads of your
electronic components, such as resistors, capacitors,
and integrated circuits, into the holes on the
breadboard. The metal
strips underneath create the connections necessary
for your circuit to function.

12. BREADBOARD POWER
SUPPLY
The Breadboard Plug-in
Power Supply Module is a
device that provides
regulated voltage rails for
project circuits on a
solderless breadboard. It can
be powered using an input
voltage range of 6.5 Volts to
12 Volts. The module has two
voltage regulators which
output 3.3 Volts and 5 Volts.

13. JUMPER WIRES
Jumper wires are wires that are used to make
connections on a breadboard. They have stiff ends that
are easy to push into the breadboard holes.
Also, it has two types of head shapes: square head and
round head.
There are several different options type of jumper
wires.
• Male-to-Male Jumper Wire
• Male-to-Female Jumper Wire
• Female-to-Female Jumper Wire

14. JUMPER WIRES
The difference between each is in the endpoint of the wire.
Male ends have a pin protruding and can plug into things,
while female ends do not but are also used for plugging.
Moreover, a male connector is referred to as a plug and
has a solid pin for centre conduction. Meanwhile, a female
connector is referred to as a jack and has a centre
conductor with a hole in it to accept the male pin.

16. SOLID-CORE HOOKUP WIRE
Although this has the same usage
as the Jumper Wire, this is much
easier to use as you can
customized the length of the wire.
You may also purchase a fixed
Hookup Wires as this will give you
more options and less time to cut
the wire yourself.
Also, this is only available as your
substitute male to male wire.

17. RESISTOR
The resistor moderates the flow of electrons, so the
current doesn't move too quickly and cause damage to
the breadboard, wires, battery, etc.
The second reason to use a
resistor is to slow the current
flow to a component.

18. LED LIGHT
The term LED is an abbreviation for Light Emitting
Diode. When current flows through an LED, it emits
light. It glows more brightly with more current, and less
brightly with less current. That takes care of “light
emitting”,

19. A diode is a one-way valve for electric current. In other
words, current can only flow through in one direction. If
the pins are reversed, no current will flow, and the LED
will not emit light. The longer (+) pin is called the anode
and the shorter one is the cathode.

because it allows components to

21. PARTS OF BREADBOARD
Breadboard have three parts:
• Power Rails: These are the rows of holes
running along the top and bottom of the
breadboard, usually marked by red and blue
lines. The red line represents the positive
voltage supply, while the blue line represents
the ground or negative voltage.
• Terminal Strips: These are the rows of holes in
the middle of the breadboard. They’re used to
connect individual components, forming the
primary part of your circuit.

23. PARTS OF BREADBOARD
• Bus Strips: Some breadboards have extra
columns, called bus strips, which can be used to
distribute power, ground, or other common
signals.

WHY DO WE NEED TO
UNDERSTAND HOW TO
BREADBOARD WORKS?

27. WHY
Understanding Hardware Prototyping: While IT
primarily focuses on software, understanding
hardware prototyping is crucial for developing
critical thinking and doing holistic solutions.
This will allow you as an IT students to experiment
with and prototype electronic circuits, which can be
essential in various IT applications such as IoT
(Internet of Things) devices or embedded systems.

28. WHY
Collaboration with Hardware Engineers: In the ICT
Industry, IT professionals often collaborate with
hardware engineers. Understanding breadboarding
allows IT students to communicate effectively with
hardware engineers, facilitating teamwork and
project collaboration.

29. WHY
Pursuing different field as Advanced Studies: For IT
Students who take interest in pursuing different
field s, this will help you to start up your
understanding embedded systems, robotics, or
hardware-centric IT specializations, proficiency in
breadboarding serves as a foundational skill.

30. WHY
Integration with Software: Many IT projects require
integration between hardware and software
components. Knowing how to use a breadboard
allows students to interface hardware components
with software applications they develop, providing
a deeper understanding of how the two interact.
