What is Arduino?

“Arduino is an open-source physical

computing platform .

based on a simple i/o board and a

development environment that implements

the Processing / Wiring language.

Arduino can be used to develop stand-alone

interactive objects or can be connected to

software on your computer.“ ( www.arduino.cc)

Arduino Hardware

College Of Engineering Attingal

College Of Engineering Attingal

•Arduino board consists of an 8-bit Atmel AVR microcontroller.

•Arduinos use the megaAVR series of chips(ATmega8

,ATmega168 ,ATmega328 , and ATmega1280)

•5 volt linear regulator

•16 MHz crystal oscillator.

•Serial Arduinos are programmed over an RS-232 serial

connection.

• USB Arduinos include an inverter circuit

(FTDI FT232) to convert between RS-232-level

andTTL-level signals and viceversa.

HARDWARE

College Of Engineering Attingal

•There are many versions of Arduino board. versions differ by size,

Microcontroller, etc

•Arduino Duemilanove, which is the simplest one to use and the best one for

learning on.

DIFFERENT FLAVOURS

Arduino footprint-compatible

boards

College Of Engineering Attingal

The 'TwentyTen' is an Arduino-compatible

microcontroller board, based on the

Duemilanove, with some improvements,

including a prototyping area, rearranged LEDs,

mini-USB connector, and altered pin 13 circuitry

The 'Illuminato Genesis', a board that uses

an ATmega644 instead of an ATmega168.

This provides 64 kB of flash, 4 kB of RAM

and 42 general I/O pins

Few examples

Boards are fully or almost fully compatible with both the Arduino hardware and

software, including being able to accept "shields". But differ on features and HW

Shields Printed circuit boards that sit atop an Arduino.

Plug into the normally supplied pin-headers of Arduino .

These are expansions to the base Arduino.

For example: Arduino Ethernet Shield,XBee Shield,TouchShield etc

Software

College Of Engineering Attingal

Integrated Development

Environment (IDE) for

programming.(Is a special program running on your

computer that allows you to write

sketches(programs) for the Arduino

board in a simple language )

•The Arduino IDE is a cross-

platform application

•The language itself is based in C

• Like a text editor

•code editor with features such

as syntax highlighting, brace matching

•View/write/edit sketches

•Verify the program by compiling

•Then upload/burn program

into Arduino board.

•IDE Details coming soon in next

classes

Arduino

Philosophy & Community

Open Source Physical Computing Platform

“open source hardware”

open source: free to inspect & modify

physical computing. err, what? ubiquitous

computing, smart objects...

Community-built

Examples wiki (the “playground”) editable by

anyone

Forums with lots of helpful people

Why Arduino?

It is Open Source, both in terms of Hardware and Software.

It is cheap, the hardware can be built from components or a prefab board can be purchased for approx 1000 rs

It can communicate with a computer via serial connection over USB /Bluetooth.

It can be powered from USB or standalone DC power.

College Of Engineering Attingal

Why Arduino?

It can run standalone from a computer (chip is programmable) and it has memory (a small amount).

It can work with both Digital and Analogue electronic signals. Sensors and Actuators.

You can make cool stuff! Some people are even making simple robots, and we all know robots are just cool.
