3. About Arduino Day
•Arduino Day is a worldwide birthday celebration of Arduino. It's a 24 hour-long event – organized directly by the
community, or by the Arduino founders – that brings people together to share their experiences and learn more
about the open-source platform.
What Can You Do During Arduino Day?
•You can attend an event or organize one for your community. It doesn’t matter whether you are a Maker, an
engineer, a designer, a developer or an educator: Arduino Day is open to anyone who wants to celebrate the
amazing things that have been done (or can be done!) with the open-source platform. The events will feature
different types of activities, tailored to local audiences all over the world.

4. Introduction of Internet of Things
The Internet of Things is simply "A network of Internet connected objects able to collect and exchange data." It is
commonly abbreviated as IoT.
The word "Internet of Things" has two main parts; Internet being the backbone of connectivity,
and Things meaning objects / devices .
In a simple way to put it, You have "things" that sense and collect data and send it to the internet. This data can
be accessible by other "things" too.

5. Open Source Software/Hardware and Platform
Open-source software is a type of computer software in which source code is released under a
license in which the copyright holder grants users the rights to study, change, and distribute the
software to anyone and for any purpose. Open-source software may be developed in a
collaborative public manner

6. What is Arduino?
The Arduino is an open-source electronics platform based on easy-to-use software and hardware. Arduino
boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an
output – activating a motor, turning on an LED, publishing something online.

7. Arduino Boards
ARDUINO MKR WIFI 1010

8. Arduino UNO

9. Getting Started
1. Download & install the Arduino environment (IDE)
2. Connect the board to your computer via the USB cable
3. If needed, install the drivers
4. Launch the Arduino IDE
5. Select your board
6. Select your serial port
7. Write Sketch (Program)
8. Upload the program

10. Arduino IDE

11. In Arduino IDE there are 6 Buttons which is used for
following:-
The check mark is used to verify your code. Click
this once you have written your code.
The arrow uploads your code to the Arduino to run.
The dotted paper will create a new file.
The upward arrow is used to open an existing
Arduino project.
The downward arrow is used to save the current file.
The far right button is a serial monitor, which is
useful for sending data from the Arduino to the PC for
debugging purposes.

12. Arduino IDE
Arduino IDE is JAVA Based
Code Compile in C and C++
Save and execute in .ino
Arduino code called Sketches

13. Arduino Programming
Variables
Like any other high-level language, a variable is used to store data with three components: a name,
a value, and a type. For example, consider the following statement:
int pin = 10;
Here, pin is the variable name that is defined with the type int and holds the value 10. Later in the
code, all occurrences of the pin variable will retrieve data from the declaration that we just made
here.

14. Constants
In the Arduino language, constants are predefined variables that are used to simplify the program:
HIGH, LOW: While working with digital pins on the Arduino board, only two distinct voltage stages
are possible at these pins.
false, true: These are used to represent logical true and false levels. false is defined as 0 and true is
mostly defined as 1.
INPUT, OUTPUT: These constants are used to define the roles of the Arduino pins. If you set the
mode of an Arduino pin as INPUT, the Arduino program will prepare the pin to read
sensors. Similarly, the OUTPUT setting prepares the pins to provide a sufficient amount of current
to the connected sensors.

15. Data types
float: This data type is used for numbers with decimal points. These are also known as floating-point numbers.
float is one of the more widely used data types along with int to represent numbers in the Arduino language:
float varFloat = 1.111;
char: This data type stores a character value and occupies 1 byte of memory. When providing a value to char
data types, character literals are declared with single quotes:
char myCharacater = 'P';
array: An array stores a collection of variables that is accessible by an index number. If you are familiar with
arrays in C/C++, it will be easier for you to get started, as the Arduino language uses the same C/C++ arrays. The
following are some of the methods to initialize an array:
int myIntArray[] = {1, 2, 3, 4, 5};
int tempValues[5] = { 32, 55, 72, 75};
char msgArray[10] = "hello!";
An array can be accessed using an index number (where the index starts from number 0):
myIntArray[0] == 1
msgArray[2] == 'e'

16. Data types
The declaration of each custom variable requires the user to specify the data type that is
associated with the variable. The Arduino language uses a standard set of data types that are used
in the C language. A list of these data types and their descriptions are as follows:
void: This is used in the function declaration to indicate that the function is not going to return any
value:
void setup() {
// actions
}
boolean: Variables defined with the data type boolean can only hold one of two values,
true or false:
boolean ledState = false;

17. Data types
byte: This is used to store an 8-bit unsigned number, which is basically any number from 0 to 255:
byte b = 0xFF;
int: This is short for integers. It stores 16-bit (Arduino Uno) or 32-bit (Arduino Due) numbers and it
is one of the primary number storage data types for the Arduino language. Although int will be used
to declare numbers throughout the book, the Arduino language also has long and short number
data types for special cases:
int varInt = 2147483647;
long varLong = varInt;
short varShort = -32768;

18. My First Program(LED Blink)
int led = 13;
void setup() {
pinMode(led, OUTPUT);
}
void loop() {
digitalWrite(led, HIGH);
delay(500);
digitalWrite(led, LOW);
delay(500);
}

20. Temperature and Humidity Sensor
#include <dht.h>
dht DHT;
#define DHT11_PIN 7
void setup() { Serial.begin(9600);
}
void loop()
{
int chk =DHT.read11(DHT11_PIN);
Serial.print("Temperature = ");
Serial.println(DHT.temperature);
Serial.print("Humidity = ");
Serial.println(DHT.humidity);
delay(1000);}

21. PIR Motion Detector and Analytics with Python
int pirPin = 7;
void setup()
{
pinMode(pirPin, INPUT);
Serial.begin(9600);
}
void loop()
{
if (digitalRead(pirPin) == HIGH)
{
Serial.println("1");
} else {
Serial.println("0");
}
delay(500);
}
