Richard Rixham introduces Arduino, an open source hardware and software platform that allows users to build physical computing devices ranging from flashing lights to robots. Arduino uses an inexpensive microcontroller board and IDE to make programming in C/C++ accessible. It has digital and analog pins that can interact with sensors and actuators. Common Arduino models include the Uno, Mini, and Mega. Shield add-on boards provide extra functions like wireless connectivity. Example projects and resources for learning more are provided.
Introduction to Arduino
- 1. INTRODUCTION TO ARDUINO Richard Rixham @richardrixham @shacknetwork Shacknetwork.co.uk
- 2. Who am I • Developer working in the Air Transporation Sector • Playing with Arduino since early 2009 • Organiser of Sheffield Arduino Hackers Network (SHACKNET)
- 3. 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
- 4. 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
- 5. 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
- 6. Other flavours of Arduino Arduino Mini Arduino Nano Arduino Lilypad Arduino Pro Arduino Pro Mini Arduino Mega Arduino Fio Arduino Bluetooth And many Clones
- 7. 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
- 8. 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
- 9. Programming Arduino • Uses other editors such as Eclipse with Arduino Plugin • RAD – Ruby Arduino Development
- 10. 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 }
- 11. Example Projects
