Hello,

In fact you are not on the proper forum for this kind of application. I translate what is displayed at the top of pages :

The LOCODUINO forum is devoted to discussions about the use of Arduino in automation and animations for model railway. We recently had some registrations of people with more general projects but mostly inapplicable to model railway. If your project or your questions do not concern model railway, do not register, you would waste your time and we too.

So I suggest you go to the official Arduino forum : http://forum.arduino.cc

Best regards
