In my project I'm controlling an EPSON printer motor. I'm using NANO circuit as my software platform using the L298 to drive the motor.
Noticed that Im not getting any improvment at the speed of the motor I found using my DVM that when I'm plug in the 12 Volt INPUT of the L298 driver to the source power it drops by Half Value.
The PCB contain all protection against BEMF or so, it's a familier one. Like in the great tutorial:
More ODD to me is that when I'm trying to work at higer voltage then 12 Volt, removing the 12 volt jumper the system stop working. no movment of the motor at all.
Hope some one can enlight me with wisdom about this issues. Thank you all.
Best Regards. Gabriel.
