I am using the EasyDriver board to driver a stepper motor. I want to also be able to turn the stepper motor by hand. I have 2 questions (as a novice).
How do I ‘release’ the stepper motor so it is easy to turn by hand as part of my Arduino sketch?
How do I prevent damaging the EasyDriver when I turn it by hand?
Thank you - this board is great
Pull the SLP pin low to disable the driver outputs.
- How do I ‘release’ the stepper motor so it is easy to turn by hand as part of my Arduino sketch?
Turn the motor slowly, Steppers generate AC power when turned by hand and the faster you turn them the higher the voltage that's produced. Turning the motor slowly will reduce the voltage and protect the driver.

Thks for the quick reply.
In regards to #2 would diodes on the stepper motor leads help?
Possibly, but they are only going to stop 1/2 of the AC waveform and will cause the motor to be hard to turn. If you put them in the wrong direction, they will short out the driver. You’re better off just turning the motor slowly.
Thank you
