Define a static variable to be used as a "time to stop" flag. Whenever you detect the tape (or whatever you use to tell when you're at the right level), set the flag. Whenever the joystick reads 127 (or close enough), clear the flag. If the flag is set, stop the motor. If the flag is clear, copy the joystick value to the motor.
