 Posting a snippet of code is generally useless. The problem is usually in another part of the program.
 
 Before posting code, please use Tools / Auto Format at the top of the IDE. It makes the code much easier to read and you will probably find it very helpful yourself. Once you've done that, use Edit / Copy for Forum.

+Always use code tags (**`<CODE/>`**) when posting code or compiler error messages.
 Using code tags makes the code easier to read and easy to copy. Not using code tags means some of the code gets displayed with smiley faces and other stuff that should not be there. Be aware that there is a limit of 120000 characters for a post. If your code takes you above this limit then you can add your .ino file as an attachment. However, it will be much easier to help you if you can write a short program that illustrates the problem you are having and post that.
 
 Please don't post an image of code instead of the code itself, or an image of error messages instead of the error messages themselves.
