When I use tone() and noTone() functions, it writes " 'tone' was not declared in this scope". Can someone help me? I am using arduino 1.5.4 Arduino Due (Programming).
Thanks for your time

When I use tone() and noTone() functions

In what code? Seems like you forgot something.

Did you put the tone.h library in your arduino user library folder?

Even when I try to compile a simple code like:

And yes, I added tone.h

You added it where? The sticky at the top of the forum, if you'd bothered to read it, tells you to post your code. We're still waiting.
