Marked as unanswered. However a reply (later converted to a comment) asking for more information has been completely ignored.
How can this ever be answered if the OP does not post code? And for other posts if the OP does not state what Arduino they have?
Suggest a "vote to close" reason: Clarification to question sought: none provided.
I'm guessing that a question that is months old, and getting no activity has been abandoned as "too hard" or answered elsewhere.
Meanwhile we get another "unanswered question" on our list.
