INSTALACION.

Buenos días.
Saludos.
Soy un principiante en este asombroso mundo de ARDUINO. no en electrónica, en la cual tengo experiencia, pero este aparatico me tiene de cabeza, tengo 5 días tratando de bajar el IDE desde la pagina oficial de ARDUINO, infructuosamente, he seguido todos los pasos indicados, sin resultado alguno, la cosa debe ser compleja ya que te advierten que es un proceso frustrante en casi todos los sitios que ofrecen asistencia para bajarlo.
Conecto la placa y lo único que hace es destellar el led conectado a la pata 13.
Pueden los ONORABLES miembros de este foro darme una mano.
Tengo el ARDUINO UNO.

Google translate made it a bit strange... But...

You can't download the IDE? It should be pretty simple to just click the links on the download page (http://arduino.cc/en/Main/Software), extract, and then run.

Connect the arduino to a usb port, then check "Board" and "Serial port" under "Tools", and you are then ready to write code for it, or experiment with the examples that follows with it.

But one thing we need to know... What OS are you using?

And last, writing in English would be help full, as I am half guessing what you wrote when I look at the translated text...

Es posible que desee intentar preguntar en este foro:

Thank, yes the google traslation is too picturesque, bud help.
Is possible that I to use a bad definition,I can download the IDE but
when I to want open the following message appear." could not find the main class:Processing. App.Base. Program will Exit. and off.

What operating system do you have?

WINDOWS XP SP 3.
SHANK.

From the troubleshooting page (http://www.arduino.cc/en/Guide/troubleshooting):

What about the error "Could not find the main class."?
If you get this error when launching Arduino:
Java Virtual Machine Launcher: Could not find the main class. Program will exit.
make sure that you correctly extracted the contents of the Arduino .zip file - in particular that the lib directory is directly inside of the Arduino directory and contains the file pde.jar.

You should try updating your version of Java.

Thank. I to try to download JABA again. I informed to you of the result.
Thank again.
