My project involves controlling 50 small stepper motors with an arduino uno to move small strips of acrylics (20x500x2mm) that act as shutters.
The stepper motor that I have is bipolar and requires 4 wires (unfortunate there is no datasheet). Hence I would need 200 inputs that would come from 25 * 74HC595. The plan is to daisy chain 25 of them, and then connect them to my L293D that I will be connecting to every motor. These will be powered by an 12V external power supply.
My question is if there would be any issues with regard to this setup. Would appreciate any help, thanks.
