What is Arduino? Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's intended for anyone making interactive projects. 

What is Arduino? A hardware to connect sensors ( inputs ) and actuators ( outputs ), an IDE to easily upload your code to the board. 

2001: Processing @ MIT Media Lab 2003: Wiring @ Interaction Design Institute Ivrea 2005: Arduino @ Interaction Design Institute Ivrea When? 

Interaction Design Institute Ivrea: Born in 2001 from Olivetti and Telecom Italia. Involved in projects like Processing, Wiring, Arduino. Dies in 2005, :'( It's successors: Domus Academy, Copenhagen Institute of Interaction Design Arduino == Ivrea 

Why? Everything you do with an Arduino can be done without. But… Which one of you is an electrical engineer/hobbyst/expert? 

Why? 

The "breadboard" Horizontal linked pin row, usually used for ground Horizontal linked pin row, usually used for voltage Vertical linked pin rows, for components The breadboard can completely replace the soldering required to setup a circuit for prototyping/learning purposes 

The Arduino Uno Digital Input/Output Pins: value 0/1 or LOW/HIGH http://arduino.cc/en/reference/board Analog Input Pins: 10-bit value 0/1023 Power Pins: 3.3V, 5V and GND Microcontroller ATmega328 Reset Button USB plug 9/12V power supply Communication feedback LED PWM ( Pulse Modulation Width ) can be used to output a voltage between 0 and 5.5V with digital pins in OUTPUT mode 

PWM http://arduino.cc/en/Tutorial/PWM Pulse Width Modulation is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between on and off. This on- off pattern can simulate voltages in between full on (5 Volts) and off (0 Volts) by changing the portion of the time the signal spends on versus the time that the signal spends off. 

Sensors Potentiometer Button Photoresistor Infrared sensor Some kind of common sensors used with Arduino: 

Actuators Led segment Servo motor Colored/RGB Led DC Motor Some kind of common actuators used with Arduino: 

The Code /* Blink Turns on an LED on for one second, then off for one second, repeatedly. This example code is in the public domain. */ // Pin 13 has an LED connected on most Arduino boards. // give it a name: int led = 13; // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); } // the loop routine runs over and over again forever: void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second } http://arduino.cc/en/Reference/HomePage Arduino is based on AVR C/C++ language. It's libraries are wrappers in C around low level hardware funcionality.

Arduino Shields Shields are boards that can be plugged on top of the Arduino PCB extending its capabilities. Need Ethernet, WiFi, Battery, GSM, GPS, Motor Control, MP3 playback, DMX, RFID, NCF, 3D laser scanner, display, LED matrix, …? Yes, there is shield for that. Or search the web / build your own!
