I’m working on a project that has two stepper motors connected to stepstick drivers. When I was playing around with the motors (not connected to anything) I attached an LED to two leads and of course it lit up. I realized that there is a big chance that in my project I would manually move the motors at some point (not turned on) and this would generate some current. Is that correct?
I was thinking of putting a rectifier diode (pos to neg lead and neg to pos lead) on both stepper leads.
Would this prevent anything flowing back to the driver board or even the Arduino.
The motors are rated at 1+amp so I picked this to be sure: DATASHEET 6A10.
Would this work and if it does, would it protect my stuff?
