How to make a weight sensor having weight as variable - Programming Questions - Arduino Forum

This may be a dumb question, but I basically know nothing about coding arduino. Basically, my project is that I need to make a weight sensor that activates a motor once a certain weight (lets say 400grams) and above has been reached. I already know how to code the motor bit, but I require assistance coding the weight as all tutorials I have found do not include the weight being a variable. I am using an hx711 and a 1kg load cell on an arduino uno. Thank you
