Arduino Compiling Error - Need Help

I am trying to get a PID sketch up and running and having an issue with compiling it

I am running windows 8 any advice would be greatly appreciated.

I attached a screen print image to help the trouble shoot.

Thanks in advance,


Post code, not screenshots. The error message says the problem lies in the code you haven't posted.

I don't know about the PID constructor but my guess on the millis error is that you forgot the () after millis.

And I've deleted the cross-post of this question to save your embarrassment.

See #7,148850.0.html

The problem is in Pid_V1.cpp, which you didn’t post.

If “millis” is unrecognised, you probably need to #include <Arduino.h> in that source file.
