capacitive touch sensor as the switch go and stop of stepper motor

I am a starter in this field.

i am using a arduino uno and L298N motor drive controller to control a stepper motor. i am wondering how can I insert the capacitive touch as the switch for the stepper motor to go ,after some time stop and if touch when moving will stop?

You need a variable - let's call it runMotor - which is normally false.

If it is false then the motor does not move.

When you touch the sensor it changes the variable to true - which allows the motor to run. When the motor finishes its run it sets the variable back to false.
