Arduino

Arduino is a free hardware circuit board with a microcontroller that can be programmed to analyze and produce electrical signals, so as to perform a wide variety of tasks such as home automation.

(control of home appliances - lighting, heating, etc.), steering a robot, etc. It's a platform based on a simple input/exit interface.
It was originally intended primarily but not exclusively for interactive multimedia programming for show or artistic entertainment. This is part of the explanation of the progeny of its Programming interface of Processing, itself inspired by the programming environment Wiring.

Arduino can be used to build independent interactive objects (fast prototyping), or can be connected to a computer to communicate with its software (example : Macromedia Flash, Processing, Max/MSP, Usine Hollyhock, Pure Data, SuperCollider).
The versions sold are pre-assembled. Information is provided for those who wish to assemble theArduino Themselves.

The project Arduino received an honorary title at theArts Electronica 2006, in the category Digital Communities.

The Arduino imprinted his name on the Bar di Re , a pub in the city ofIvrée, located in northern Italy. The proper name Arduino has just Ardennes.

A module Arduino is built around a microcontroller Atmel AVR

Description

A module Arduino is usually built around a microcontroller Atmel AVR (ATmega328 or ATmega2560 for recent versions. ATmega168 or ATmega8 for the oldest), and additional components that facilitate programming and interfacing with other circuits.
Each module has at least a 5 V linear regulator and a 16 MHz quartz oscillator (or ceramic resonator in some models).
The microcontroller is pre-programmed with a bootloader So what a dedicated programmer is not necessary.

The modules are programmed through a serial RS232

RS232

For a serial line information arrive at regular intervals (synchronous) or at random intervals (asynchronous). Between a transmitter (DTE) and a receiver (DCE) wiring is right. RS232 cables can be connected in series.
In configurations where 2 DTE are directly connected, a cable of cross linking or \Null-Modem\ should be used. This cable has female connectors at each end.

The USB bus is also said to \Hot pluggable\, that is to say that you can connect and disconnect a USB with the PC on. The system installed on the PC (Windows, linux...) recognizes it immediately. The USB has a very interesting feature : it's the mode standby when not using the device. Also known as \Power conservation\ : Indeed the USB bus gets suspended after 3 ms if it is no longer used. During this mode, the co

-serial module (as a card or cable).

The Arduino uses most of the inputs/outputs of the microcontroller for interfacing with other circuits. The model Diecimila for example, has 14 input/output digital, whose 6 can produce PWM signals, and 6 analog inputs.
Connections are made through female connectors HE14 located on top of the map, the plug-ins from piling on theArduino. Several kinds of extensions are available in the trade.

Software

The programming of the modules software Arduino is a free Java application and cross-platform, using code editor and compiler, and who can transfer the firmware and the program through the serial (RS232

depending on the module).
It is also possible to dispense with the interface Arduino, and to compile and upload programs via the command line interface.

The programming language is C++, compiled with g ++, and linked to the development library Arduino allowing the use of the card and its inputs/outputs.
The implementation of this standard language makes it easy the development of programs on platforms Arduino, to anyone mastering the C or C++.

The origin of the different versions of the Arduino modules are manufactured by the Italian company Smart Projects. Some of the cards of brand Arduino have been designed by the American company SparkFun Electronics.

The different versions of Arduino operate under the same general principle

Operation

The different versions of Arduino operate under the same general principle :

A : these are digital said feet (0.1) or \all or nothing\; They offer the 5V output and accept input from the 5V on the same principle.
function digitalWrite() and digitalRead()

B : analog say legs, value between 0V and 5V function analogWrite() and analogRead()

C : different legs of power :

Red : out (+) 5V

Orange : exit 3, 3V (+)

Black : the masses (-)

Yellow : entry related to food (7V - 12V)

There are variations between the different cards (ex : ) UNOleg 13 is equipped with a resistance)

3D printing is an additive production technique developed for rapid prototyping. Its goal is to quickly and easily generate a physical piece. Different materials can be used, more generally ABS plastic, PLA plastic, and metal, but also wax, or even plaster.
The applications of 3D printing are varied, but in all cases aim to concrete visualization of projects, or verification of parts ergonomics. 3D printing works
