Imperial March on Dot Matrix Printer

I continue to torment the new musical printer. Today it is about what I have long been asking for - Imperial March from Star Wars. Asked me to do it on a floppy disk drives, but I will do this song on printer. By the way, the answer to what it works - Arduino, and driver transistors. I tried to show it all close up, so you can see this simple scheme. =================== SUBSCRIBE:
