Connect 5V ULN2003 28BYJ-48 4-Phase Stepper Motor input wires to Arduino pins (in my case 31, 33, 35, 37) and +5V and GND according to the picture below.  |

Insert a new Stepper device like the picture below, define the pins of the arduino you want to use like the picture below and configure the settings.  In the next picture you see the compass offset:  And the values that work for me:  In Case your Compass turns in the wrong direction, than in Interpolation settings use the values 0 - 360 360 - 0 When you start the Sim, make sure to move the motor to the N position using the Manual calibration section by clicking the button move (last picture). Once the needle is on the letter N, click the button Set Zero and you are set. |

Hi AlbEagle,
Thanks for the Whisky Compass 3D files,just completed it. How did you find the stepper motor's operation. My ones(3) seem to have a
certain amount of slop in the gearbox. This slop is magnified when the disk is added resulting in a shaky readout while turning.
Did you find this in your steppers. If so how did you overcome it.
Regards
Les

Regards Les Hi there Les The stepper I have is a cheap one from ebay and it doesn't have any slop. If you watch the video it rotates great, check it here: Here is the link from the stepper i have bought: Link for Stepper on ebayRegards AlbEagle |

Hi,
Thanks for replying, that's the same type i have. The disc that i printed from the files on your site is pushed onto the shaft and you
apply a little pressure at the perimeter of the disc you will see a variation of about 3 to 4mm. So i really don't know what the diff is between our gauges are. I proved it was slop in the gearbox by dismantling the motor and packing it with grease. Now the problem is
gone. You must have got lucky with your one as all three have the same problem.
Thanks anyway, the grease seems to have stayed in place.
Regards
Les

Hi,
On the photo it shows a 5v connection. from the motor board and the ardunio board. Could you tell me what could be used to power this? Is there enough volts from the ardunio that It could be powered from?
Cheers

Yes, the power supply from the Arduino board is sufficient for the stepper motor.

I would always power it externaly, i have a Powersupply (fixed_) for all 5volt and 12 volt parts of the sim.
