Arduino Arduino Arduino Software

L ' Arduino IDE is an application platform written in Java , and is derived created by the IDE for the programming language and Processing for the project Wiring . It is designed to introduce artists and other newcomers to programming, fasting practice in software development. To enable the writing of source code . The card also includes a text editor has some special features such as syntax highlighting , control of the way, el ' indentation automatic. The editor is also able to compile and run the executable program in one pass and with a single click. Generally there is no need to create Makefile or run programs from the command line .

L ' integrated development environment Arduino is provided with a software library C / C + + called "Wiring" ( homonymous project Wiring ), which makes it much easier to implement common tasks in software input / output. Arduino programs are written in C / C + +, but in order to create an executable file, the user is not asked anything except define two functions :

• setup () - a function invoked only once at the beginning of a program that can be used for the initial settings
• loop () - a function called repeatedly until the card is turned off.

And here is a simple program that turns on an LED:

  # include "WProgram.h"  

  # define LED_PIN 11  

  void setup     ( ) {   

  pinMode   (  LED_PIN  ,   OUTPUT  )  ;   / / enable pin 11 for digital output  

 }  

  void   loop   (  ) {   

    digitalWrite (  LED_PIN  ,   HIGH  )  ;   / / LED lights  

  delay   (    1000)  ;   / / wait 1 second (1000 milliseconds)  

    digitalWrite (  LED_PIN  ,   LOW  )  ;   / / off LED  

  delay   (  1000  )  ;   / / wait 1 second  

 } int main     (    void) {   

    init ( )  ;  

  setup   ( )  ;  

  for   ( ;;  )  

    loop   ( )  ;  

  return       0;}    

"WProgram.h" is the header file main library for Wiring, and function main () makes only three distinct calls: init (), defined in the same library, and functions setup () and loop (), defined by the user. The latter, as required, is automatically nested in a loop.
