Stepper Motor Locking

I am using stepper motors for a school project, but right now the motors are locking up when I give them power. If I turn down the external power to 3V it is not locked, but it’s also not enough to power the motors. When I give the motors the necessary 12V it locks up and can’t move. Are there any things I can do or test to try and fix this?

Then they are working properly. You need a stepper motor controller attached to the stepper motor wires and the controller attached to your Arduino and a test program running in the Arduino to make the stepper move.

Do you have all this and properly powered?

Yes, I have a easydriver connected to both the motor and arduino and I have a test code

Please read and follow the directions in the "How to use this forum" post.

Stepper motors hold position. That's their function.

By changing the position by 1 step (or a fraction of a step), they hold a new position. Repeat rapidly to produce movement. Give no stepping commands and the motor holds firmly until the power is removed.
