As the title suggests, I have many "expected `)' before ';' token" errors. The issue is, I have this stuff in. So now I am confused, why am I getting this if the things are there.

I am new here and had an issue with adding code, so here is the pastebin link to it: http://pastebin.com/4WXxsXkB

And here is the the pastebin link to the error: http://pastebin.com/QyehP86M

Does anyone understand how this could happen?

    #defines do not have a ';' after them try removing these Commented Nov 4, 2014 at 19:37

1 Answer 1


You have two #define statements at the top of your code

#define trigPin 3; 
#define echoPin 2;

The way #define works is that it replaces every instance of the name with everything after it on the line so trigPin is being replaced with 3; as opposed to 3 as intended.

Fixing this should solve some of your problems.
