stack two 2A Motor Shields to control two stepper
woqisiyasi 2015-06-25 19:36:40 5725 Views3 Replies Good morning, everyone:
Was wondering if you have any ideal how to control two steppers separately using two shields ?
I stacked two shields together and each shield links with a 28BYJ-48 stepper motor. Since the pin settings for the board are the same and all commands are sent to both shields, these two steppers working in the same manner. For example, they turn clockwise at the same time. My idea is to block one board from the other. When the commands have been sent, one board receives but one ignores the commands. How should I achieve this ?
I also need some suggestions for the sketch programming.
If you have other suggestions for controlling two steppers, for example, using other motor shield or connecting method, please also let me know. Thanks in advance.

Are you using the Stepper Motor Shield，https://www.dfrobot.com/index.php?route=product/product&product_id=1060&search=step&description=true&category_id=48#.VYt7N_kQjj9this can be used to control two steper seprately
the code is from its wiki page:
