Hi Thanks that worked, no idea why I did not think of it! ULN2003 Stepper Motor ,yes it is a uni-poplar stepper motor but changed by following the instructions break the red wire circuit under the blue plastic cover at this sitehttps://simvim.com/tech_28byj.html .
Hi Thanks I made the changes you suggested I am getting a small partial turn. I have used smaller numbers "shootingsteps" 2,4 6. rather then the 10,20, 40 numbers.I read some more on easy drivers and realized the easy driver default to 1/8 step, read more still not sure how to change it to full step? I do not understand how to "You can pull either or both to ground" Is it in the physical wiring or in the code?"You can pull either or both to ground to select the other 3 modes if you want. See the table below:"http://www.schmalzhaus.com/EasyDriver/MS1MS2ResolutionlowlowFull Step (2 phase)highlowHalf steplowhighQuarter stephighhighEight step
Hi I have a Stepper Motor 28BYJ-48 that I would like to use it has enough torque to turn my platform that I ran on another program. Waht in the code would I need to change?I know the Stepper Motor 28BYJ-48 each step corresponding to a rotation of 11.25 degrees according to the datasheet. That means there are 32 steps per revolution (360/11.25 = 32). In addition, the manufacturer has specified a gear ratio of 64:1 for the 28BYJ-48 stepper motor. To obtain the final number of steps, the gear ratio must be multiplied by the number of steps per revolution, 32. The more accurate value for the gear ratio is actually about 63.68395 : 1. Therefore, we set the final number of steps to 2038 (32 x 63.68395 = 2037.8864).
where can I find the code in english--Thanks
