discovered that teachers who are proficient in using digital
tools could help students develop higher-order thinking
skills, give them unique and creative ways to express what
they have learned, and better prepare them to deal with
ongoing technological change in both the real world and the
workplace. India needs cost-effective and cutting-edge
educational equipment to support this revolution in
education. An essential part of STEM education is
technology. We created affordable educational laptops for
teachers, students, and schools. This laptop is user-friendly
and has strong connectivity and processing power. The
physical computing feature will improve the young students'
programming abilities and creativity.
Key Words: Raspberry Pi, Laptop, Operating Systems,
Supercomputer, Affordable, Programming.
1. INTRODUCTION
Information technology is a rapidly evolving field that
frequently offers the public new solutions. To
communicate, distribute, create, store, and organize
information, schools use a variety of ICT tools. The use of
smartphones and tablets or tablet computers for having to
learn during lectures, as well as the "flipped classroom"
model, where pupils watch live and documented lectures
at home on the smart device and use class time for more
interactive activities, are some examples of how ICT has
sometimes become an integral part of the teaching-
learning process. These methods can promote higher-
order thinking skills, offer unique and personalized ways
for learners to express their identities, and keep students
better equipped to deal with continuing technological
changes in both the globe and the workplace when
instructors are digitally literate and trained to use ICT.
Devices like the Raspberry Pi are often used as examples
of this phenomenon. Engineers were able to create a low-
cost, hand computer with convincing technical
specifications thanks to ongoing miniaturization and
inexpensive components. These microcomputers can
perform a wide range of tasks, from industrial applications
to domestic entertainment. The Raspberry Pi Foundation
raised the bar even further by questioning themselves to
create a flexible tool to raise the caliber of IT instruction.
This project demonstrates how a low-cost project can give
educational institutions new capabilities that will enable
them to give students opportunities to learn how to
develop and use applications that they will come across in
the future. The project's independent project-based
structure turned out to be a crucial element in its
successful design and execution.
The construction of large cluster computers has become
affordable thanks to the availability of low-cost, high-
power single-board computers like the Raspberry Pi. This
paper outlines a cheap and simple method for giving
students programming experience on supercomputers
without using simulation or visualization methods. To
help readers understand the benefits of writing
programmes to make use of parallel computer
architectures, a sample prime search programme created
to run on a multi node cluster is provided along with run-
times.
In this paper, we suggest a low-cost laptop for education
that has the distinctive capability of physical computing.
Raspberry Pi, a single-board computer, was used in the
design of this laptop. This device is compatible with a
number of programming languages, including C, C++,
Python, Java, and Scratch. It offers top-notch software for
performing office tasks like creating spreadsheets, word
processing, and presentation preparation. It uses an open
source operating system based on Linux and can be used
for both educational and non-educational purposes.
2. PROBLEM STATEMENT
A new area of the digital world arises due to the current
epidemic COVID- 19 which is being faced worldwide, while
the world is still espousing social distance practice. System
Technology takes a step ahead in order to deal with this
issue where nearly all of India is working from home.
scholars of seminaries/sodalities are floundering to
manage with expensive tackle(Laptop/ Desktops). To
overcome this challenge, I've come up with the exceptional
idea of using a low- cost bias which can save millions of
dollars on a laptop/ desktop.
More and more students are looking for opportunities to
gain experience with emerging technologies that

personally interest them but may go beyond the intended
curriculum. This essay examines a single, independent
project in which a student used the parallel processing
power of ten Raspberry Pi devices to build a
supercomputer. The value of this paper lies in its
understandings of how impartial tasks may be used for
students to gain outside of the education system to
increase their intellectual presence in the field, how to
nurture a comprehensive community of learners for the
immediate society, provide a way for learners to earn
course credit without causing financial hardship for the
college, and at last this specific project of building a
supercomputer
Numerous people have started to use ‘Raspberry Pi 4 B
with Raspberry Pi OS’. This helps to connect to their online
classroom, surf the internet, connect office systems to
virtual machines, and has power for real multitasking and
productivity.
In our opinion, the classroom can greatly benefit from the
inexpensive, quick, intuitive, engaging, and long-lasting
physical computing solutions available today. The
raspberry pi is one of many integrated, carefully crafted
physical computing devices that has the potential to firmly
establish physical computing as a crucial component of
contemporary computer science education. These board-
level embedded devices should eventually have greater
computational power, better wireless connectivity, better
physical construction kit integration, and greater
extensibility. They will also probably become less
expensive and smaller than current products, which will
make them even better suited for a range of school
projects and uses like wearable technology, robotics, and
gaming.
In the natural and environmental sciences, data collection
is easily supported by physical computing devices. The
next generation of scientists will be engaged and educated
as physical computing devices—natural sources of sensor
data—become more and more relevant in the rapidly
developing field of data science. Finally, both students and
amateurs can be given the tools they need to start a
maker-to-market journey in a variety of application
domains.
But there are still a lot of difficulties. Teachers and
technology developers must work closely together to
design an end-to-end experience that is compelling for
both students and teachers. A seamless and engaging end-
to-end experience depends on tight hardware and
programming environment integration. Of course, it is also
imperative to have high-quality curriculum, instruction,
and teacher preparation.
3. LITERATURE SURVEY
Only 26.42% of Indian schools have computers, according
to a government survey conducted by the Department of
School Education & Literacy and National University of
Educational Planning and Administration (NIEPA). In
India's 36 states and union territories, 1.52 million schools
were included in the report for the academic year 2014–
15. Students in secondary schools have a critical need for
an affordable educational laptop to learn about
fundamental programming and physical computing. This
gadget will give students in schools an easy way to learn
programming and physical computing.
The abundance of excellent educational apps and websites
that can be accessed is undoubtedly a benefit of computers
being so widely used. Learning can take the form of
entertaining and instructive games, movies, and lessons
that will help students advance their understanding of
everything from vocabulary to mathematics, typing to
logical reasoning, and everything in between. Atal
Tinkering Labs (ATLs) were established by the Indian
government in a number of locations to offer makers and
innovators cutting-edge facilities. This ATL's requirement
for physical computing devices and computers in large
quantities can be satisfied with a cheap and simple device.
Physical computers with computing capabilities are
extremely rare. Three products that are currently on the
market are similar: Pi-Top, ExpEYES (previously known as
Phoenix), and BBC micro:bit. The BBC micro:bit is a
practical programmable computer that includes Bluetooth,
motion detection, and a built-in compass. With its built-in
compass or "magnetometer," 25 LEDs, two programmable
buttons, and five input/output ports, the Micro:bit can be
connected to other devices or sensors. To students in the
UK between the ages of 11 and 12, BBC distributed about 1
million devices. Because the BBC Micro:bit lacks a display,
programming requires a computer or laptop. A cheap
platform for computer-assisted science experiments is
called ExpEYES. It is created by the New Delhi-based Inter-
University Accelerator Center.
It has 50 experiment GUIs, 12 bit analogue input/output,
digital input/output, time interval measurements,
waveform generation, and test equipment functionality.
The best feature of this device is that its hardware is open
source, but programming it also necessitates a computer
or laptop. In the end, it serves as a cheap platform for
scientific experiments. A modular laptop called the Pi-top
offers resources for developing creative do-it-yourself
(DIY) projects and bringing inventions to life. The system's
brain is a Raspberry Pi single-board computer. A quad-
core Arm cortex processor running at 1.4GHz, four USB
ports, 40 GPIO pins, an HDMI port, Gigabit Ethernet port,
wireless LAN (Wi-Fi), and a display interface are all

included. This device costs about 27000 INR, which is a
very high and nearly identical price.
For students, this is a cost-effective laptop for learning,
tinkering, and conducting experiments whenever and
wherever they like. They can be liberated from lab hours
and, in some cases, get around the issue of individual
students' need for equipment. For presentations,
demonstrations, experiments, and the creation of new
experiments, projects, and prototypes, teachers and
educators can use their personal laptops. Engineers can
pick up skills in sensor interfacing, GUI programming,
physical computing, electronics, microcontroller
programming, computing, and a variety of programming
languages. Hobbyists can purchase a nice device to pass
their time more efficiently. This tool can be used by
innovators to demonstrate concepts and create original
products.

The micro:bit offers an experience that is accessible to
beginners but also offers a lot of headroom for more
advanced usage, including as an embedded controller in
class and hobby projects. The micro:bit packs a lot of
functionality into a small and reasonably priced package.
The Raspberry Pi is a logical next step for those looking to
move beyond the Micro:bit. It's more difficult to set up but
supports a wide variety of applications, making the Pi an
incredibly versatile general-purpose computer. The Pi is a
self-contained, Linux-based computer. There are a number
of models, including the Raspberry Pi 3 Model B+ and the
most recent Raspberry Pi 4.
Connecting a keyboard, mouse, monitor, SD card, and USB
power supply to a Pi is the first thing to do. Raspian, the
operating system for the Raspberry Pi, must be installed
on the SD card. The 40-pin connector on the Pi is intended
for connecting to actuators, sensors, and other physical
computing devices.
By using software and hardware that can sense and react
to the analogue world, physical computing is characterized
as "the construction of interactive physical systems." It
links together a variety of mechatronics-related tasks.
Computer science, robotics, electrical engineering, and
embedded development. Physical kits based on
microcontrollers and the usage of computers in
educational contexts is common for a long period of time
for environmental research and scientific interactive art,
robotics, and sensing. Electronic prototyping is
particularly popular with Arduino. For customers to create
interactive electronic things, it offers a software package
and hardware. computers with just one board, such as the
Raspberry Pi, in comparison to platforms that use
microcontrollers. We interact with SBCs, additional
storage is provided via the display or displays. Strong
process power and capability. Memory cards are needed
for SBCs that have an operating system installed, ready for
use as a computer.
4. PROPOSED SYSTEM
The system's single board computer (SBC) is its core
component. Memory, a processor, LAN and WiFi
interfaces, and an audio/video interface make up the SBC.
For storing data and loading the operating system, use a
memory card and otherwise internal memory. The open
source nature of Linux and the abundance of free software
make it a viable option for operating systems. Graphical
user interface (GUI) can be presented on a standard HDMI
monitor or touch screen when used as a display device.
When a display doesn't have a touch screen, a standard
USB keyboard and a mouse are used as the input devices.
A single board computer (SBC) offers an external
peripheral interface (GPIO) to connect different sensors
and electronics parts

6. CONCLUSIONS
"Building interactive physical systems by using software
and hardware that can sense and respond to the analog
world" is the definition of physical computing. Electrical
engineering, mechatronics, embedded development,
robotics, and computer science are all interconnected by
physical computing. For years, academic institutions have
made extensive use of physical computing devices and
toolkits based on microcontrollers for robotics, interactive
art, environmental sensing, and scientific experimentation.
A well-liked platform for electronic prototyping is
Arduino. It offers users hardware and software packages
so they can create interactive electronic objects.
Comparing single-board computers like the Raspberry Pi
to such microcontroller-based platforms, there are
advantages. SBCs, with their additional storage capacity
and high processing power, are connected to displays or
monitors. SBCs are tiny computers, so in order to function
as a computer, a memory card must be loaded with the
operating system.

This computer is developed to be used for educational
purposes. It can be used to make word documents,
spreadsheets & presentations. It can also pierce the
internet and connect people to the vast amount of
resources available. It can be used for learning to write
codes, developing software, building circuits, developing
projects, etc. Its main advantage is its portability and
affordability. It has a manufacturing cost so low, that it is a
lot cheaper than most computers. Therefore, a greater
number of people can afford them. Raspberry Pi’s
performance is compared with some of the more popular
boards and development platforms across the board by
size, computing power and overall costs of the software
solutions. Based on performed analysis, it can be
articulated that Udoo, has the best performances among
all of the considered IoT hardware platforms, but at the
same time its price is relatively high. On the other hand, A
detailed analysis on the Raspberry Pi has shown that it's
the perfect platform for a PC in the area of sensor network.
That is why it makes Raspberry Pi the perfect platform for
interfacing with a wide assortment of external peripherals
and is used in a broad scope of implementations.
Communications and Information Technology can affect
how well students learn. According to the most recent
research, we discovered that teachers who are proficient
in using digital tools can help students develop higher
order thinking skills, give them unique and creative ways
to express what they have learned, and better prepare
them to deal with ongoing technological change in both
the real world and the workplace. India needs cost-
effective and cutting-edge educational equipment to
support this revolution in education. An important part of
STEM education is technology. We created affordable
educational laptops for teachers, students, and schools.
This laptop is user-friendly and has strong connectivity
and processing power. The physical computing feature
will improve the young students' programming abilities
and creativity.
