How to make stepper motor clockwise and anticlockwise

Other Hardware Motors, Mechanics, Power and CNC

I want to make a system where when the LDR and rain sensor receives a voltage above 300, it gives a command to the stepper motor to move clockwise. And when LDR and rain sensor gives voltage below 300, the stepper motor will turn anticlockwise and another stepper motor that is attached to a DIY fan will also turn. But why does both condition make the motor turn clockwise?? please help me

Can you get the motors to turn both ways if you run the library examples?

What does your serial output say?

Where are you getting power for the steppers?
