BUT have you thought about generating the DTMF via arduino? Here is a cool recreation of a blue box, and does all kinds of tones as used on many different systems- http://www.instructables.com/id/Arduino … roduction/ I had the same thoughts, and plan to build this. Really dig some of the beats by ElmerCat https://soundcloud.com/elmercat/didja Yogi So this might work for you without the second phone- http://www.instructables.com/id/Simple- … ed-Phones/]]>https://chipmusic.org/yogi2016-02-07T23:40:32Zhttps://chipmusic.org/forums/post/239373/#p239373<![CDATA[Telephone + DTMF]]>Hi!
I am working on a sound performance involving a telephone. I want to use the telephone to generate DTMF tones without being connected to a phone line. Is it possible ? How ?
