Hi all, I have been working on this program and cannot seem to figure it out. First off I am using arduino 0021 for this program. It contains a clock and temperature program. Both programs work separately but when combined I get only 1 message at the end of it. I get this :
expected unqualified-id before '{' token Here is the code:
