I am a newbie on Arduino. I have Arduino Mega 2560 and want to drive 12 bipolair stepper motors ( L298 as driver). My questions are:
- Can I use directly the arduino pins 2 to 49 to drive the L298 or it should better to use the 74HC595?
- how can I calculate the total limit courant and which paramaters must taking to drive my stepper motors?.
please I am harry to start my project. please help me as soon as possible.
