Any advice how to control 3 stepper motors (nema 17)?

Hello, I am new at this forum and don't have experience with arduino so I need your help. I want to build spirograph with 3 stepper motors. The part which is difficult to me is how to connect 3x stepper motors to arduino uno using 3x a4988 drivers. Also I want to have different and adjustable spinning speed at every motor. Should I need to use potentiometers for that ? Wiring diagram would be really helpful thing :slight_smile: Thank you guys!

P.S I know that there are videos at youtube how to connect stepper motor to arduino, but at every video people connecting only one stepper motor and writing code only for one motor. That's why I need your help guys.

Please check your motor data sheet(s) for the required voltage and current!

The motor movements are fully controlled by software - see the Stepper or AccelStepper library examples. For multiple motors you need multiple stepper objects. The pot is for current limiting only. Wiring is easy, each module requires one pin for the steps, and one pin for the direction.
