Musical scanner in musical floppy controller? #36

Hello, Could it be possible to connect scanner like musical floppy to play like on this video https://www.youtube.com/watch?v=NJQ2LpUYqqE Thanks for reply.

Hello! Yes! I recommend controlling your scanner stepper with a DRV8825 and use the standard Moppy instrument interface. If you search "DRV8825 wiring" on Google, you'll find some documentation. If you have a high resistance stepper, you can also use the L298N.

Do I need the RESET and SLEEP pin of the DRV8825 with Moppy or have I only to connect it like a floppy with the STEP and DIR pin?

Lothean commented 5 years ago

STEP and DIR are the only signals you need to interface with Moppy Just pull RESET and SLEEP high and it works :)

Kisko93005 commented 5 years ago

Hello! I've got L298N module, just how to connect it to arduino if I need a dir and step pin.

Lothean commented 5 years ago

You need to use the L298N instrument instead of the default FloppyDrives one. The pinout is in L298N.h

Kisko93005 commented 5 years ago

Ok, I connect l298N to the arduino but the motor in scanner is overheating! Please help! The motor is: mitsumi M35SP-11NK LF

Lothean commented 5 years ago

That's because at 12V, your 15 Ohms motor is drawing 800mA although it is rated 360mA at peak. You cannot lower the input voltage since :

So you need to use a DRV8825 current limited driver; which uses the standard Floppy instrument and interface.

Ok I bought DRV8825 on monday ,but the musical scanner works exellently with 7 floppy drives.
