dwattel:
Thanks, that did the trick.But can someone explain me the difference between print and println?
"print" just sends what it's told to send. "println" sends the content, plus a newline (i.e. CR/LF).
To clarify, if you are sending the string "123" to an LCD, "print" (or "write") will send, in hex:
31, 32, 33
If you use "println", it sends this:
31, 32, 33, 0D, 0A
The last two characters make a serial terminal move to the next new line, but to an LCD, they are just gibberish.
Make sense?
