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.
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

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.
Arduino Shields Arduino GSM Shield
Arduino Shields Arduino Ethernet Shield
Arduino Shields Arduino WiFi Shield
Arduino Shields Arduino Motor Shield
How does Arduino work? Write a code in your computer
Upload it to the Arduino board
Arduino board can the be used standalone
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

Arduino IDE Examples
Examples Blinking led
Examples Blinking led
// Example 01 : Blinking LEDconst 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
Examples Blinking led
Examples Blinking led with switch
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
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); } }
