i am thinking of doing a project which involves a arduino and programming. As i am new to this, I don't have a deep knowledge of how to do this stuff. So i need a programming/sketches on how to interface a usb barcode scanner to arduino so that whenever the barcode scanner scans a barcode, (which is connected to the arduino) it's output is displayed on pc.
I don't have a deep knowledge of how to do this stuff.
You will by the time you are finished.
how to interface a usb barcode scanner to arduino
For that you will need a USB host shield, but you will probably have to write the software drives for this which will be complex and involve you knowing exactly how the bar code scanner works, which might not be easy to find out.
I would spend about at least 6 months getting up to speed before you look specifically at this project.
