Hi,
I'm probably duplicating other questions, but I didn't manage to find anything about this on the Internet.
Automatic phone bots often allows you to enter numbers to make choices etc. How are these numbers transferred?
And is it possible to capture these on an Arduino?
A link or two on the topic would be very much appreciated!
