Sorry if i am being vague but i am new in the world of programming.My purpose is to make a connection by 4 Arduinos. I want each one to control a motor. The power suply tha i use is by usb port. I want to send g-code and the right one arduino can read it so I can run it.If it is possible i want all 4 arduinos to run when i send them a .txt file with its ID.What I have in my mind is feasible or i'm thinking in a wrong way? I am sorry if any information is missing.Thank you for understanding.
