You would have to change the code significantly to switch to steppers, as they require a totally different driving method. Also, you would need to change the circuit to add a stepper motor driver to it.

Buy this to drive the steppers (assuming the steppers dont draw too much power):

The code wont need to be changed much with this driver.
