One of our microcontrollers assignments was to use a digital potentiometer as a digital to analog converter. We were given a file with thousands of numerical values, and had to use a digital potentiometer to convert the values to an analog voltage, and using an audio connector and headphones/speakers, had to identify the song. In addition, a potentiometer is used to change the playback speed.

Sorry about the fact that the audio is kinda low.
