Thank you sanjaykray!

Hi gizmologist,The rotary dial mechanism is connected to pins A1 and A2. See constants ROTATE_PIN and COUNTER_PIN and all the code around these constants in "telephone.ino" file.The rotary dial mechanism has three wires: groung and two signals. One is a "flag" that the mechanism is rotating and the other is a pulse counter. I just count logical 0 to 1 (or 1 to 0, can't remember right now) transitions while the rotation flag is set to detect every digit of the phone number.As I said this is an open project, you can find the source code on the project's GitHub page.

Exactly!
