scanner to L298N

[zseawq123452]

I connected the scanner and the L298N
However, when executed, the scanner motor only makes a small sound, and the header does not move. Which one more need to be modified?

I don't have any experience with L298Ns, so I can't help too much. Can you manually trigger the L298N, and does it work as expected then? (I.e. is the issue on the L298N-side of things, or the Arduino side of things)

[zseawq123452]

Yes, I solved the low sound of the motor. But still, the header doesn't move. Is there anything I can modify in the code?

[Sammy1Am]

You'll need to figure out what the issue is (the head not moving is just a symptom) before we can really talk about modifications.

Are you able to manually trigger the L298N (using the signal lines you've hooked to the Arduino) and get it to move?

[zseawq123452]

Yes I triggered it manually and it moved.

Alright, it sounds like the connection from the L298N to the scanner is fine then. My only additional troubleshooting tips are:

• Confirm that you commented the #define INSTRUMENT_FLOPPIES line, and you that you uncommented the #define INSTRUMENT_L298N line in MoppyConfig.h.
• Double check that there are no errors in the Arduino IDE when you upload the firmware (sometimes it's very subtle about its failures)
• Double check the connections to the Arduino. If there's any ambiguity, maybe try a different pin? (I've never connected an L298N so I don't really know anything about the pinout)

As far as I can tell, the code is mostly correct as others (see #113) are currently having success.
