Hi first of all thanks so much for sim hub what a great product I use it daily for bass shakers. I added rumble pedals to my logitech 920 and it worked great for a week and then the motors stopped working. I'm pretty sure I over powered them. I got replacement ones on the way. In the configuration what frequency for two motors should I be using I think I left it on the default. I had the effects of the motors at 50 percent and had road effects + speed but when I did stock car in iracing I was thinking man its really rocking haha. So on the second go around should I keep everything at 25 percent possibly? One motor died before the other one, before they both died I switched the ports on the motor shield to make sure it wasn't the ardunio/motor shield. I'll list my hardware I used too any input would be great thanks. Pretty sure my main problem was that it showed 4 motors when two where connected and I didn't know the Frequency to use in the setup. Thanks again!

 

LM YN Motor Stepper Servo Robot Shield v2 with PWM Driver Shield for Arduino(I configured it with the adafruit one was that right?).

I soldered the connections so pretty sure that's not the issue these motors are cheap enough I don't mind replacing them but would be great to figure it out. I am ignorant of calibrating the hardware. Thanks again!

I'm using the DK motor shield, but I am also running the motors at 12v, 100% no problem. So I'm not sure if the motors are your problem. I am using the generic "Xbox controller rumble motors" that a lot of sellers are selling on Ebay, I think they actually are rated for 12v, even if they only run 3.7 or 5v in the controllers.

When you configured the arduino in sim hub what frequency did you use? Thanks for the reply....not sure what else it could be I think the motors where fine I just overdrove them somehow....the sodered connection looks fine still. I'll find out in a day or two when the new ones come in.

You will find out when your new motors arrive. 🙂 You could of course also test the old motors by connecting them directly to a power source. That is probably the best way to sort out where the fault lies.

There is no separate PWM frequency setting for the DK motor shield, so I'm just using the default there. Not sure what frequency it is.

But I don't think that the wrong PWM frequency could kill a motor? More likely that a too high PWM frequency would overheat and kill transistors in either the motor board or the arduino. I would just use the suggested default value of 1900 Hz (which is max).

Have you removed the yellow power jumper on the motor board? It needs to be removed to use external power.
