Content-
1.Introduction
2. Basics of Arduino
3.Basic of Electronics
4. Interfacing basic I/O Devices
5. mini Projects

WHAT IS ARDUINO?
1. Arduino refers to an open-source electronics platform based on easy and flexible to
use
Hardware or Software.
) 2.An Arduino board consist of at Atmel-8bit AVP microcontroller(which is responsible for
all type of computation
ORIGIN OF ARDUINO?
1. Arduino was born in 2005 in Italy.
2. Named “Arduino” in honour of Bar di Re Arduino.
3. Massimo Banzi, Co-founder of the Arduino Project.
4. Idea behind this project is, Less Expensive device for
controlling interactive electronic project.

Components of Arduino boards
Digital I/O Pins
1.In Arduino board there are 14 digital pins.
2.It take digital input and give digital output.
Analog Pins
1.Here 6 Analog Pins which are capable to handle
environmental data in Analog form various Sensor.
Microcontroller
1.It is a central component in Arduino, which are responsible for all type of
computation.
Power Pins
1.These Pins provide power to Arduino with an unregulated 7to12v power source.

Types of Arduino board
Arduino Board is used for making different engineering projects and
different applications
It’s software is very simple to use for beginner and it is flexible
It can run smoothly on Window ,Linux, Mac operating systems.
1. Arduino Uno (R3)
2. Arduino Nano.
3. Arduino Micro.
4. Arduino Due.
5. LilyPad Arduino Board.
6. Arduino Bluetooth.
7. Arduino Diecimila.
8. RedBoard Arduino Board.
9. Arduino Leonardo Board
10.Arduino Ethernet
11.And many more………

Most Used Arduino Boards
Arduino UNO(R3)
It is most frequently used board
Very useful for beginners
It is inexpensive and small in size and easy to carry
It works on ATmega328P based microcontroller
It consist of 14 digital I/0 pins,6PWM, 6 Analog , SPI,UART12C
Arduino Nano
As name specify it is smaller in size.
Based on ATmega628 microcontroller.
We can connect with mini USP and Arduino IDE.
IT having 8 analog pin and 14 digital pin with set of I/o pin .
Reset button and all other additions of separate pins also.

Selection of Boards
This decision is made based on the requirements of user.
The best way to select the Arduino boardis to check I/O and computing
requirements.
For beginners Arduino uno is best boardto make initial project.
Each board varies based on the input/output ,speed, voltage voltage etc.
Requirements of voltage to operate these boards range from 3.7 to 5 volt.
Original Arduino Uno is Italian made.
And in Indian markets several clone of Arduino uno Is available

TYPES OF SIGNAL IN ARDUINO
1.Analog Signal
The signal like our voice, light, temperatures all thees called Analog Signal .These are
continuous in nature and can have any real value.
2.Digital Signal
Computers does not understand Analog Signal , So we have digital Signal in form of 0
and 1 or HIGH & LOW .

TYPES OF PIN IN ARDUINO BOARD
1. Digital Pin
2. Analog Pin
3. Pulse With Modulation(PWM)
4. Power Pins
5. Serial Communication Pins
6. And Pins which can work with interrupt signal
PWM
Pulse with modulation is used to get specific output.
PWM going to control the duty cycle of our output digital way.
Serial Communication Pins
D0 &D1 pins are known as Serial Communication Pins.They will have
transmitter as well as receiver.
Interrupt Pins
It has specific function which need to be triggered ongoing
operation can be connected on these pins

SUPPORTED LANGUAGE IN ARDUINO
The Arduino Programming language is built on top of C++
In Arduino Programming a Program is called Sketch.
Sketch is consist of Two main Function.
1.Set up function
Basically to set thing up for the purpose of initialization.
It is used to define initial condition.
2.Loop function
A function which contain loop is called Loop Function.
Basically loop function is used for purpose of “Iterations”
A Loop can be finite as well as infinite.

IMPORTANT WORDS INVOLVING IN ANY SKETCH
Variable
In any sketch variables are the name of memory location where we store
data, and a variable name can not start with a “Number”.
String
In simple words if we define it then it is “Set of Characters”
It can be a symbol in double coats.
Naming a Variable
In Arduino name of a variable should be a single word and Mathematical operators
are not allowed.
Assigning Values
We first declare data type of given variable and then assigning value by using the
equal sign.

FIRST SKETCH IN ARDUINO UNO
Printing anything as any Noun on Serial
Monitor

SOME USEFUL BASIC COMMANDs
1 pinMode(pin number, MODE);
Pin Number: Integer that specify pin number
MODE:INPUT/OUTPUT
Example: pinMode(13,INPUT);
2 digitalWrite(pin number, STATUS);
Pin Number: Integer that specify pin number
STATUS: HIGH/LOW
digitalWrite(9,HIGH);

PRINTING SET OF CHARACTERS “ STRING” ON Serial Monitor

CONCATINATION IN USING ARDUINO INTEGRATED DEVELOPMENT ENVIRONMENT
(IDE)
Here, basic meaning of concatenation is adding two strings in a single sketch.
Plus sign(+) may be used to append one string to another.

CONDITIONAL STATEMENT
As name specified, conditional statement it is based on condition
Here, two popular conditional statement are if(),else

PROGRAM BASED ON If-else STATEMENT

TONE GENERATION
If there is something which is moving and its moving around it at a constant
rate/sec.
It is going to generate some sound. We called “Tone”

BREADBOARD
In Arduino we need something to connect electronic components and breadboard is
one.

CIRCUIT DIAGRAM FOR PRINTING NAME ON LCD

SKETCH FOR LCD PRINT WORD “LIMITLESS”

DC MOTOR ON TINKERCAD
It is a static device which convert electrical energy into mechanical energy.
CIRCUIT DIAGRAM SKETCH

CONNECTION OF MULTILPE GEAR MOTOR ON ARDUINO WITH
BREADBOARD

FINAL PROJECT
PASSWORD PROTECTED DOOR LOCK
