any help running six stepper motors? Answered

i have six stepper motors and i am planning to build a robotic arm. is it possible to build a driver curciut to run the six motors from an arduino to make the arm move. if its not possible then how would i build a controller to drive six uln2003 driver chips

https://www.instructables.com/id/How-to-wire-an-arduino-based-3-axis-CNC-machine/ shows controlling three steppers. Extending the concept to six should be a straightforward exercise. If you run out of control pins on the Arduino, you may need external registers and a bit of addressing circuitry, but I think the Arduino can probably handle all six without that complication.

Of course you also need to write the software to cycle the output lines through the appropriate states. But that's a Simple Matter Of Programming.
