Once again Australian Arduino enthusiast Beau Walker has created an interesting and fun project. In this example the device is a simple Arduino-controlled telephone exchange for use with classic Telecom rotary phones.
Not only can each phone dial and connect with the other, the Arduino controls an external 90V signal which is required to activate the original ringers in the phone. Apart from fun for younger people, this could also be the framework for a simple phone-based intercom for larger homes, workplaces or farms.

If you need to add external hardware or devices to your next Arduino project, you'll need a protoshield to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega we have a wide range to suit your application.
