The whole project is as follows: I'm trying to build a Django based web-app for my college library. This app when idle will be showing a slideshow of pictures on the screen. However when an input is received from the barcode scanner, it is supposed to redirect it to a different age containing information related to that barcode. I'm not able to figure out how to get an input from the scanner and only then redirect it to the page for 3 seconds containing the relevant information, after the interval, it should redirect back to the page containing the slideshow.
