As a gift for their daughters in the holiday season, Arduino forum member "rediculum" came up with an interesting spin on the classic toy telephone. They've created a simple device can can play sound files from a memory card on demand from an Arduino board, and the file can be chosen by dialling a number using an old rotary telephone dial.
Once the electronics are fitted inside the telephone housing this would make a fun object for many young children. In the meanwhile, the device is demonstrated in the following video:
If you're not interested in fairy tales, this project demonstrates how simple it is to use an old rotary phone, and also the PCM library to play .wav files without much effort.
