Hi just wondering, I need to power six 12v stepper motors from my Arduino Uno to power a robotic armfor my project and I was looking at using easy driver stepper motor drivers but I will need six of them but could I use a quadstepper motor driver board and if so, do I still need an easy driver stepper motor.
Thanks.
How many motors do you need ?
If you said six, then why are suggesting four ( quad) ?
sorry that is my fault I did not know I could get one to run six motors but just after finding one, so all I would need is a signal from the Arduino and a power supply to the stepper motor driver to power the motors ?
You need to be sure the stepper motor driver board can comfortably supply the current required by your motor.
Each stepper motor driver board will require a step and direction connection to the Arduino. If you have a circuit board with 4 stepper drivers then that will require 4 step and 4 direction connections.
Are you sure you shouldn't be using servos with a robotic arm?
...R

Your comment above leads me to believe you have absolutely no idea (no clue) how to control a stepper motor with an arduino.
Can you guess why I would say such a thing ?
Have you or have you not already tested a stepper motor ?
We need to know this information to determine what to tell you.
You have not given us a situation report.

suggests you are new to both arduino and steppers and have not as yet done anything or have any experience. Is that correct ?
If not , could you please update us with your arduino/electronics background ?

That's eight signals (not one) . For six motors you would need 12 signals. (d1 --> d13) which leaves no pins available for anything else like sensors. If you use a Mega2560 you have many more I/O pins.
