Short Description:
Long Description:	The operator of an escape room asked us to update an old rotary phone so it would play a message if the right number was dialed, and a busy signal if the wrong number was dialed. This could be adapted as an audio tour guide for a museum
How we did it / geekery:	We gutted the phone case of unneeded components, determined how to get a signal of the rotary dial and installed [[electronics]] for an [[arduino]] to read this signal. We replaced the speaker in the headset with one that is headphone compatible. We installed an MP3 player that would play either a dial tone, busy signal, or the message, based on signals from the Arduino. We [[Programming\|programmed]] the software to run a dial tone when the receiver is lifted, interpret the signal to a number dialed, and to play the message or the busy signal based on the number dialed. The MP3 board didn't initially have all the functionality I wanted broken out to the driver, so I updated it and contributed it back to [https://github.com/sparkfun/SparkFun_WT2003S_MP3_Decoder_Arduino_Library its github repository].
