Who am I
Developer working in the Air Transporation Sector
Playing with Arduino since early 2009
Organiser of Sheffield Arduino Hackers Network (SHACKNET)

What is Arduino
Arduino is Lego turned up to 11
Open Source hardware platform
Open Source software and libraries
Physical Computing, allowing interaction with the environment
Build anything from a flashing light to robots that can interact with the internet
Inexpensive and FUN 

What is an Arduino
14 Digital Pins (6 PWM) Reset USB Connector External Power Supply Power Pins 6 Analog Inputs Power LED ATmega AVR TX/RX LED

Arduino Specification
Microcontroller ATmega 168/328
Clock Speed 16 MHz
Operating Voltage 5V
Digital I/O Pins 14 (6 provide PWM output)
Analog Input Pins 6
Flash Memory 16 KB (Atmega168) or 32 KB (ATmega328) of which 2 KB used by bootloader
SRAM 1 KB (ATmega168) or 2 KB (ATmega328)
EEPROM - 512 bytes (ATmega168) or 1 KB (ATmega328)
Provides I2C and SPI

Other flavours of Arduino
Arduino Mini Arduino Mini Arduino Nano Arduino Lilypad Arduino Pro Arduino Pro Mini Arduino Mega Arduino Fio Arduino Bluetooth And many Clones

Arduino Shields
Shields are boards that can be plugged in to provide additional capabilities
Examples Xbee – Wireless connectivity DMX – Control lights Ethernet, GPS, Bluetooth
Shieldlist.org

Programming Arduino
Language based on C/C++ linked to AVR-libc library http://www.nongnu.org/avr-libc
Open Source Libraries (LCD, string)
Official IDE written in Java
Runs on Windows, Linux and MacOS

Programming Arduino
Uses other editors such as Eclipse with Arduino Plugin
RAD – Ruby Arduino Development

Hello World
int ledPin = 13; // LED connected to digital pin 13 void setup() { pinMode(ledPin, OUTPUT); // sets the digital pin as output } void loop() { digitalWrite(ledPin, HIGH); // sets the LED on delay(1000); // waits for a second digitalWrite(ledPin, LOW); // sets the LED off delay(1000); // waits for a second }
