stack two H-Bridge Shields to control two stepper

Post by zs96742 » Thu Jun 25, 2015 2:18 am

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 ?

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.

To use two HBRIDGE shields at once with different motors - you would need to clip the headers for D2~D7 on the second shield and run jumpers over to six more digital pins (e.g. D8~D13) and use those to control the second shield.
