The Automatic Harmonica player
The automatic harmonica player was built by 3 engineering students as a senior project. It went from idea on a piece of paper to built in under 12 weeks.
The device is operated using a keypad on which 10 keys directly corrospond to the 10 holes of the harmonica. There is also a key to turn the system (LCD and keypad) backlighting on/off as well as 4 keys mapped to preprogrammed songs in the microcontroller. When the user selects a song or plays a note, the note or song is displayed on the LCD.
The user can also create their own songs to play using a windows interface which was developed in Visual C++ or select from a list of existing songs for playback.
There is a 10 minute 40mb video of the device in operation here: http://www.purplehippo.com/ed2/ED2%20-%20Automatic%20Harmonica.wmv
