3. What is Arduino?
 Open Source physical computing platform you can make your own board, or
buy one.
 Arduino is an open-source platform used for building electronics projects.
 Arduino consists of both a physical programmable circuit board (often
referred to as a microcontroller) and a piece of software, or IDE (Integrated
Development Environment) that runs on your computer.
 Very widespread, many projects openly available.
 Extra HW (shields) available.

4. Why Arduino ?
 Well documented , a lot of examples and a great community
 Open source Hardware/Software
 Work on different OS
(Linux , Windows and Mac)
 USB connection
 Cheap

5. Types of Arduino
 Arduino Uno
 Arduino Mega
 Arduino Leonardo
 Arduino micro
 LilyPad Arduino USB
 Arduino Pro Mini
 Arduino Fio
 Arduino Robot

6. Arduino Uno

7. Arduino Uno
 Microcontroller ATmega328
 Digital I/O Pins 14 (of which 6 provide PWM output)
 Analog Input Pins 6
 Clock Speed 16 MHz
 USB connection to PC via printer cable
 Power from USB or external power supply

8. Arduino Mega

9. Arduino Mega
 Microcontroller ATmega2560
 Digital I/O Pins 54 (of which 15 provide PWM output)
 Analog Input Pins 16
 Clock Speed 16 MHz
 USB connection to PC
 Power from USB or external power supply

17. Arduino Shields
 Shields are boards that can be plugged on top of the Arduino PCB extending
its capabilities. The different shields follow the same philosophy as the
original toolkit: they are easy to mount, and cheap to produce.

18. Arduino Shields
 Arduino GSM Shield

19. Arduino Shields
 Arduino Ethernet Shield

20. Arduino Shields
 Arduino WiFi Shield

21. Arduino Shields
 Arduino Motor Shield

22. How does Arduino work?
 Write a code in your computer
 Upload it to the Arduino board
 Arduino board can the be used standalone

23. Arduino Language
 C like syntax, but simplified
 Abstracts the pin naming to numbers
 Trades efficience for ease of use
 Easy to learn, yet powerful
 Lots of example code
 Easy to reuse C-code from other projects
 Libraries can be written in C++
 Lots of libraries available

25. Arduino IDE
 Examples

26. Examples
 Blinking led

27. Examples
 Blinking led
// Example 01 : Blinking LED
const int LED = 13;
void setup ()
{
pinMode(LED, OUTPUT);
}
void loop ()
{
digitalWrite(LED, HIGH);
delay(1000);
digitalWrite(LED, LOW);
delay(1000);
}
Declare variables
Initialize pins i/o
Program body

28. Examples
 Blinking led

29. Examples
 Blinking led with switch

30. Examples
 Blinking led with switch
// Example 02 : Blinking LED With Switch
const int ledPin = 13;
const int buttonPin = 2;
int val;
void setup ( )
{
pinMode(ledPin, OUTPUT);
pinMode(buttonPin, INPUT);
}
Declare variables
Initialize pins i/o

31. Examples
 Blinking led with switch
// Example 02 : Blinking LED With Switch
void loop()
{
val = digitalRead(buttonPin);
if (val == HIGH)
{
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
}
else {digitalWrite(ledPin, LOW); } }
