Music Box

The musical instrument box is equipped with a keypad that communicates with Raspberry Pi over I2C so that users can play instrumental sounds through an external speaker by pressing the buttons, of which each button responses to a certain note. The notes list includes C4, D4, E4, F4, G4, C5, D5, E5, F5, G5, A5, B5, C6, D6, E6 both piano and guitar notes. The musical instrument box provides three modes for users, namely free mode, guide mode, and record mode. In free mode, users can play pre-set notes freely. In guide-mode, users can pick and load a song from melody lists and play the whole song by pressing buttons following the order the LEDs flash. In record mode, users can still play music just like in guide mode. The music box will record the notes and duration for each notes that the user played and make playback of what the user played.
