Arduino Controlled Musical Scanner Motor

[TRS-90]

I want to start a project where I make some scanners and 555 wave generators play a song but I can't find a code example where to notes and pauses are directly coded by the programmer instead of using a MIDI file.


All I want to do is make the scanner stepper motors play the main part of the song and the 555 wave generators play the background tune by being switched on and off by the arduino.

I plan on using 2 scanners playing the same notes at the same time to make it a bit louder without having to record and then amplify the song (I can do that, it's just I don't want to HAVE to).

I will probably buy a motor controller shield for my arduino if that helps.
