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.
