From what I’ve m35so, I believe I have to connect the stepper to an external power supply, but I could not find any reference on how to do that and I’m afraid of doing it wrong and destroying my Arduino. It is working, I would say, but the thing is that the stepper is too weak Sorry about the lack of proper technical term.

I wish everyone took the time to explain their problems so clearly! You are right, though, that an external supply is preferred as powering a motor directly from the Arduino is not a good idea.

If it’s closer to 8 ohms, you have the 6V version and should use a 6V external supply. I would move the external power supply ground black wire closer to the ground wire for the ULN near pin.

Take the black wire from the 24v supply out of the board where you have it and place it directly next to pin 8 on the darlington driver.

Hierarchical block is unconnected 3. I also tried to google the specs on yours, but couldn’t find any real reference about its existence. Hi Cassiano, I read in your post that you are using a Mitsumi M35SP-7T stepper motor and you show in your image 5 wires from motor to circuit.

How do you n35sp an MCU design to market quickly? So at the moment I am using the motor as a bipolar one whereas the manual says unipolar with a puls rate of Hz.

First of all, thanks a lot for the answer!

Losses in inductor of a boost converter 9. Might as well make that path as short as possible.

Here is my circuit: At what frequency are you using your motor? So from the data sheet of Mitsumi I guess that the motor 9r on 6 V.

This particular motor has only 4 wires and on the label it is written 9 Ohms. Any help is greatly appreciated. Synthesized tuning, Part 2: Digital multimeter appears to have measured voltages lower than expected. There are two ways of implementing a stepping motor, one uses two coils 4 wires and the m35s uses four coils 5 wires See: That was THE fastest reply ever!!!

I’ll go and do some work now. ModelSim – How to force a struct type k35sp in SystemVerilog? It should be 50 ohms approximately according to the datasheet. After spending half of my day just trying to find out how to use it with the Arduino which in my case involved learning what a stepper is and how it works and all of the different kinds of steppersI was finally able to setup a working circuit based on Tom Igoe’s explanation found here: Maybe the T would explain the sOhms.

Indeed mine has 5 wires.
