TROUBLESHOOTING
CODE PROBLEMS: COMPILE ERRORS
Compile errors are revealed when you attempt to compile your code and the Arduino software (the compiler) finds a problem. The software then displays an error message in the status bar that may give you a hint about the cause of the error. You will not be able to upload your program until you fix the problem. Common causes of compile errors include missing semicolons, missing curly brackets, misspellings, and mis-capitalizations. See troubleshooting solutions page for more information on compile errors and how to find and fix them.
