Problem in LOAD Cell , Motor , Ultrasonic sensor

I have a problem in creating code connect load cell ,motor and ultrasonic sensor which when ultra sonic sensor detect an object from 4 cm stop the motor then load cell take it's weight after that if the weight of the object is meeting the requirements the motor turn on else the motor won't move until this object someone take it away from above the load cell

Do you have code testing EACH of those devices, individually?

yes I did

Good. The is the first step. NOW, what exactly, in words, are you trying to accomplish. The words will have the logic needed for your project.
