Re: DTMF decoder library

I can not compile using Arduino Web Editor and Arduino/Genuino Micro.

This is the error: “DTMF.h: No such file or directory”

Any ideas on How to solve?

Dear Supremo,

I am testing the library you did and it works just fine. I have a question. How I do to turn off any led after it was lit (tone detected) using a pre-difined delay? Thanks for your orientation.

This a Programming Question. It's not about the DTMF library.
