how to control unipolar stepper motor with esay driver
Not possible. The Easydriver stepper driver is for bipolar motors.
Post a link to the datasheet for your stepper motor. Some motors can work as bipolar or unipolar

Stepper Motor Basics
I have a stepping motor type:(4H4018S2003) 6 wire and I have other stepper from salvage.
The number of your motor means nothing to me. You need to provide a link to its datasheet.
6-wire motors can usually work as bipolar or unipolar. Did you read my link?
How many wires has the salvaged motor got?
What is the resistance (ohms) of the coils?
What did it come from?
How big is it?
Post a photo of it.

If you have a circuit diagram for your 6-wire motor uni-polar motor, then it should be possible to ignore the centre-tap wires (leave them disconnected), and treat the motor as a bipolar motor. Then just drive the bipolar configuration with your bipolar driver.
Don't exceed your bipolar driver's recommended power handling specifications and things should be ok.
