Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino projects can be stand-alone or they can communicate with software on running on a computer (e.g. Flash, Processing, MaxMSP).
Inexpensive - Arduino boards are relatively inexpensive compared to other microcontroller platforms. The least expensive version of the Arduino module can be assembled by hand, and even the pre-assembled Arduino modules cost less than $50
Cross-platform - The Arduino software runs on Windows, Macintosh OSX, and Linux operating systems. Most microcontroller systems are limited to Windows.
Simple, clear programming environment - The Arduino programming environment is easy-to-use for beginners, yet flexible enough for advanced users to take advantage of as well. For teachers, it's conveniently based on the Processing programming environment, so students learning to program in that environment will be familiar with the look and feel of Arduino
Open source and extensible software - The Arduino software and is published as open source tools, available for extension by experienced programmers. The language can be expanded through C++ libraries, and people wanting to understand the technical details can make the leap from Arduino to the AVR C programming language on which it's based. SImilarly, you can add AVR-C code directly into your Arduino programs if you want to.
Open source and extensible hardware - The Arduino is based on Atmel's ATMEGA328 and ATMEGA168 microcontrollers. The plans for the modules are published under a Creative Commons license, so experienced circuit designers can make their own version of the module, extending it and improving it. Even relatively inexperienced users can build the breadboard version of the module in order to understand how it works and save money.
The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter."Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduno, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform
There are multiple versions of the Arduino board. The previous basic board, the Duemilanove, uses the Atmel ATmega328 microcontroller. The older Diecimila, and the first run of Duemilanoves used the Atmel ATmega168, while older boards use the ATmega8. The Arduino Mega is based on the ATmega1280. A microcontroller is a computer-on-a-chip. It is a type of microprocessor dedicated to execute one task embedded in another device to control the features of that device.
Duemilanove - The Duemilanove automatically selects the appropriate power supply (USB or external power), eliminating the need for the power selection jumper found on previous boards. It also adds an easiest to cut trace for disabling the auto-reset, along with a solder jumper for re-enabling it. Around March 1st, 2009, the Duemilanove started to ship with the ATmega328p instead of the ATmega168.
Diecimila - The main change in the Arduino Diecimila was that it can be reset from the computer, without the need to physically press the reset button on the board. The Diecimila uses a low dropout voltage regulator which lowers the board's power consumption when powered by an external supply (AC/DC adapter or battery). A resettable polyfuse protects your computer's USB ports from shorts and surges. It also provides pin headers for the reset line and for 3.3V. There is a built-in LED on pin 13.
Nano - A compact board designed for breadboard use, the Nano connects to the computer using a USB Mini-B cable.
Mega - A larger, more powerful Arduino board, shield compatible with the Duemilanove and Diecmila.
Bluetooth (pictured) - The Arduino BT contains a bluetooth module that allows for wireless communication and programming. It is compatible with Arduino shields.
LilyPad - Designed for wearable application, this board can be sewn onto fabric, and is a stylish purple. details
Mini - This is the smallest Arduino board. It works well in a breadboard or for applications in which space is at a premium. It connects to the computer using the Mini USB Adapter.
Mini USB Adapter - This board converts a USB connection into 5 volt, GND, TX and RX lines that you can connect to the Arduino Mini or other microcontroller.
Pro - This board is designed for advanced users who want to leave a board embedded in a project: it's cheaper than a Diecimila and easily powered by a battery, but requires additional components and assembly.
Pro Mini - Like the Pro, the Pro Mini is designed for advanced users requiring a low-cost, small board and willing to do some extra work.
Serial - It's a basic board that uses RS232 as an interface to a computer for programming or communication. This board is easy to assemble even as a learning exercise.
Serial Single Sided - This board is designed to be etched and assembled by hand. It is slightly larger than the Diecimila, but still shield compatible.
Since the name "Arduino" is a protected trademark, branding products as Freeduino allows users to build on the established knowledge and open-source licenses of the Arduino project without having to worry about trademark infringement.
Adafruit Motor/Stepper/Servo Shield pictured). Shields generally are bought as a kit of parts to be assembled.
This a prototyping shield for you to solder your own circuits on to. It is a more permanent platform than a solderless breadboard but still fits on top of an Arduino board, unlike a regular protoboard.
