I am currently working on a project to build a barcode scanner. I have built the apparatus to detect a signal and am able to view this signal on an oscilloscope, however I am wondering if it is possible to build a circuit to output this signal as a binary code on a series of LED's (or something of that nature...)? You might of guessed im not very proficent with electronics, so I came here for help! This signal is the same form as on http://www.thekeeser.com/Projects/bar_code_reader.htm" [Broken] but of a continous nature. I was thinking of putting the signal through some sort of Analogue to Digital convertor and then using some sort of counter to output this signal on a display, maybe a series of LED's representing a binary code? The readout doesn't have to be that accurate, just as long as it kind of works... Could this be done? How? Any help would be much appreciated!
