help with a multiple arduinos project

Projects General Guidance
1

Hello,
I'm a computer science student and I just started degsining my final project.
I'm new to arduino so I need help with design the implemenation of several things (just to be clear,
I have no HW knowledge).
The things I need for my project are:

  1. Barcode Scanner (probably an arduino with a usb shield)
  2. Weight Scale (do not know how to implement, but needs to be pretty large, maximum of 100kg)
  3. Program (can be on another, third, device) that recieves both devices (1. and 2.) output.

Thank you in advance for all the future helpers.

You could easily do 1 and 2 on a single Arduino.

I don't know what you mean by 3.

How can I easily do 1 and 2? Again, I have no knowledge at hardware.
In 3 I ment that I want to recieve the output of the scanner (I.e the barcode) and the output of the weight scale (I.e the weight) to the same program (which can be implemented and run on another device).

I presume if you are a student you understand the concepts of research and learning. You need to find suitable sensors and you need to learn how to program an Arduino to collect data from the sensors.

In 3 I ment that I want to recieve the output of the scanner (I.e the barcode) and the output of the weight scale (I.e the weight) to the same program (which can be implemented and run on another device).

This is still pretty meaningless. What is this program supposed to do with the data, and why? What device is it to run on?
