steppermotor turntable 180 degr

I have a tuntable and when I pressed a button the turntable must turn 180 degrees, then stop for a few seconds, then it must turn180 degrees anticlockwise then stop. Wait for the next press on the button.

how can it be done?

Very easy. Fire up the IDE, and start typing.

You can't expect us to help you, because you failed to define what kind of stepper motor driver you are using, how it is connected to the Arduino, how it is powered, how many steps it takes to rotate one full revolution, which pin the button is sewn onto, etc.

Using a switch would be so much easier...
