where system failures could have severe consequences. Therefore, they are engineered to be
highly reliable and resilient, incorporating features such as fault tolerance, redundancy, and
error detection and recovery mechanisms. Examples include medical devices, aerospace
systems, and automotive safety systems.
1.4 Introduction to Embedded Systems
An embedded system is a specialized computing system designed to perform
specific tasks within larger devices or systems. Unlike general-purpose computers,
which are versatile and can run a wide range of applications, embedded systems are
tailored to execute predefined functions efficiently and reliably. They are typically
embedded into devices and equipment to control, monitor, or interact with various
aspects of the physical world.

17. Key Characteristics:
● Dedicated Functionality: Embedded systems are built to perform specific
tasks, such as controlling industrial machinery, managing automotive systems,
monitoring environmental conditions, or processing data from sensors.
● Real-time Operation: Many embedded systems operate in real-time, meaning
they must respond to input signals or events within strict timing constraints.
This capability is crucial in applications where timely and predictable
responses are required, such as in automotive safety systems or medical
devices.
● Resource Constraints: Embedded systems often operate under resource-
constrained environments, including limited processing power, memory, and
energy. They are optimized for efficiency to meet performance requirements
while minimizing hardware costs and power consumption.
● Integration with Physical World: Embedded systems interface with the
physical world through sensors, actuators, and other peripherals. They acquire
data from sensors, process it, and control actuators to interact with the
environment, enabling automation and control in various applications.
1.5 ?
Our eyes are drawn to colors and patterns. We can quickly identify red from
blue, and squares from circles. Our culture is visual, including everything from art
and advertisements to TV and movies. Data visualization is another form of visual art

18. that grabs our interest and keeps our eyes on the message. When we see a chart, we
quickly see trends and outliers. If we can see something, we internalize it quickly.
Data visualization is the practice of translating information into a visual context, such
as a map or graph, to make data easier for the human brain to understand and pull
insights from. The main goal of data visualization is to make it easier to identify
patterns, trends and outliers in large data sets. The term is often used interchangeably
with information graphics, information visualization and statistical graphics.
Data visualization is one of the steps of the data science process, which states
that after data has been collected, processed and modeled, it must be visualized for
conclusions to be made. Data visualization is also an element of the broader data
presentation architecture discipline, which aims to identify, locate, manipulate, format
and deliver data in the most efficient way possible.
Data visualization is important for almost every professional discipline.
Teachers use it to display student test results, computer scientists to explore
advancements in artificial intelligence (AI). Data visualization provides a quick and
effective way to communicate information in a universal manner using visual
information. Business professionals have different areas and levels of expertise, but
visualizations are meant to be understandable by anyone. Visualizations make it easier
for employees in an organization to make decisions and act based on insights derived
from them.

19. CHAPTER 2
Prerequisites
2.1 Introduction to C language
C is a powerful and widely used programming language known for its
efficiency, versatility, and portability. Developed in the early 1970s by Dennis Ritchie
at Bell Labs, C has become one of the most influential programming languages in
history, serving as the foundation for many other languages and systems.
Key Characteristics:

20. 1. **Procedural Language**: C is a procedural programming language, which
means that it follows a top-down approach to program design, emphasizing
procedures or functions to accomplish tasks.
2. **Structured Language**: C supports structured programming constructs
such as loops, conditionals, and functions, allowing for modular and organized code
development.
3. **Mid-level Language**: C strikes a balance between high-level and low-
level programming languages. It provides low-level access to memory and hardware
features while also offering high-level abstractions for programming tasks.
4. **Efficiency**: C is renowned for its efficiency in terms of both execution
speed and memory usage. It allows programmers to write code that runs close to the
hardware, making it suitable for systems programming and performance-critical
applications.
5. **Portability**: C programs can be easily ported across different hardware
platforms and operating systems with minimal modifications. This portability is
facilitated by standards such as the ANSI C standard (also known as C89 or C90) and
subsequent revisions.
6. **Extensibility**: C is highly extensible, allowing programmers to
incorporate assembly language code or interface with libraries written in other
languages such as assembly, C++, or even higher-level languages like Python.
Basic Syntax:
Variables and Data Types: C supports various data types, including integers,
floating-point numbers, characters, arrays, structures, and pointers. Variables must be

21. declared before use, specifying their data type.
Control Structures: C provides constructs for flow control, including if-else
statements, loops (for, while, do-while), and switch statements.
Functions: Functions in C are blocks of code that perform a specific task. They
can take parameters as input and return values as output. C programs typically include
a main() function, which serves as the entry point of the program.
Pointers: Pointers are variables that store memory addresses. They allow for
direct manipulation of memory and facilitate dynamic memory allocation and
efficient data manipulation.
Arrays and Strings: C supports arrays, which are collections of elements of the
same data type stored in contiguous memory locations. Strings in C are represented
as arrays of characters, terminated by a null character ('0').
Applications:
C is used in a wide range of applications, including:
- System software development (e.g., operating systems, device drivers)
- Embedded systems programming (e.g., microcontrollers, firmware)
- Application software development (e.g., desktop applications, games)

2.3 Installation of Softwares(Arduino IDE, Proteus)
Step 1 − First you must have your Arduino board (you can choose your
favorite board) and a USB cable. In case you use Arduino UNO, Arduino
Duemilanove, Nano, Arduino Mega 2560, or Diecimila, you will need a
standard USB cable (A plug to B plug), the kind you would connect to a USB
printer as shown in the following image.

26. In case you use Arduino Nano, you will need an A to Mini-B cable
instead as shown in the following image.
Step 2 − Download Arduino IDE Software.
You can get different versions of Arduino IDE from the Download page on
the Arduino Official website. You must select your software, which is
compatible with your operating system (Windows, IOS, or Linux). After your
file download is complete, unzip the file.

27. Step 3 − Power up your board.
The Arduino Uno, Mega, Duemilanove and Arduino Nano automatically draw
power from either, the USB connection to the computer or an external power
supply. If you are using an Arduino Diecimila, you have to make sure that
the board is configured to draw power from the USB connection. The power
source is selected with a jumper, a small piece of plastic that fits onto two of
the three pins between the USB and power jacks. Check that it is on the two
pins closest to the USB port.
Connect the Arduino board to your computer using the USB cable. The
green power LED (labeled PWR) should glow.
Step 4 − Launch Arduino IDE.
After your Arduino IDE software is downloaded, you need to unzip the folder.
Inside the folder, you can find the application icon with an infinity label
(application.exe). Double-click the icon to start the IDE.

28. Step 5 − Open your first project.
Once the software starts, you have two options −
● Create a new project.
● Open an existing project example.
To create a new project, select File → New.
Step 6 − Select your Arduino board.
To avoid any error while uploading your program to the board, you must
select the correct Arduino board name, which matches with the board
connected to your computer.
Go to Tools → Board and select your board.

29. Here, we have selected Arduino Uno board according to our tutorial, but you
must select the name matching the board that you are using.
Step 7 − Select your serial port.
Select the serial device of the Arduino board. Go to Tools → Serial Port
menu. This is likely to be COM3 or higher (COM1 and COM2 are usually
reserved for hardware serial ports). To find out, you can disconnect your
Arduino board and re-open the menu, the entry that disappears should be of
the Arduino board. Reconnect the board and select that serial port.

30. Step 8 − Upload the program to your board.
Before explaining how we can upload our program to the board, we must
demonstrate the function of each symbol appearing in the Arduino IDE
toolbar.

31. A − Used to check if there is any compilation error.
B − Used to upload a program to the Arduino board.
C − Shortcut used to create a new sketch.
D − Used to directly open one of the example sketch.
E − Used to save your sketch.
F − Serial monitor used to receive serial data from the board and send the
serial data to the board.
Now, simply click the "Upload" button in the environment. Wait a few
seconds; you will see the RX and TX LEDs on the board, flashing. If the
upload is successful, the message "Done uploading" will appear in the status
bar.
Note − If you have an Arduino Mini, NG, or other board, you need to press
the reset button physically on the board, immediately before clicking the
upload button on the Arduino Software.

33. CHAPTER 3
WORK DONE

34. 3.1 TASK PERFORMED
3.1.1 Password Based Door Lock System using 8051 Microcontroller
Here, we developed an electronic code lock system using 8051
microcontroller (a Password based Door Lock System using 8051
Microcontroller), which provides control to actuate the load. It is a simple
embedded system with input from the keyboard and the output being
actuated accordingly.
This system demonstrates a Password based Door Lock System using 8051
Microcontroller, wherein once the correct code or password is entered, the
door is opened and the concerned person is allowed access to the secured
area. Again, if another person arrives, it will ask to enter the password. If the
password is wrong, then door would remain closed, denying access to the
person
Principle Behind the Circuit
The main component in the circuit is the 8051 controller. In this project, a
4×4 Matrix Keypad is used to enter the password. The password which is
entered is compared with the predefined password.
If the entered password is correct, then the system opens the door by
rotating the door motor and displays the status of the door on the LCD. If the
password is wrong, then the door remains closed and displays “PWD is
wrong” on the LCD.
