The 40 drives are powered by the Arduino mega. There are two channels. I know, I should have made 4 or more, but at this time I just implemented 2.
Pretty cool accomplishment. However I strongly suspect that the PC power supply is doing the powering of that project and the Arduino is just doing the controlling of the project? That may sound picky but a lot of people (especially beginners) have trouble separating those two functions and assume they can place a burden on the a Arduino board that it can never met.
Again cool project and sorry for one of my pet peeves.
I am wondering if I have to do anything different on arduino Mega then the Uno.
I am thinking that I have to change the pin # in the codes for a musical floppy drive sense the Uno has less pins then the Mega
Alright so i have got a Micro in stead of mega. I finished the Moppy project and it seems to be working but when ever i load midi files, it always plays the bass, or never plays at all. Here is a video of my Moppy drive trying to play i need your love by calvin harris or something - YouTube
