I have a bar-code reader with a PS/2 interface, so connecting it to the Arduino will require a PS/2 keyboard-style connection and software. Sounds like you’ve already found that! Building a bar-code scanner with an LCD looks like quite a do-able thing.
This is kinda OT, but I actually started a tear down of a barcode scanner game a while ago. I’ve actually got more photos somewhere that include showing how the scanner uses very simple hardware for the scanning part.
I remember reading a tutorial on how to do barcode scanning with a LED/photosensor and a cheap PIC microcontroller. Certainly an atmega168 would be up to that task. However, to save you the headache you might want to pick up a used bar code reader. Here in the US you can get the CueCat scanners cheaply on ebay. The interface is identical to that of a PS/2 keyboard. http://cgi.ebay.com/NEW-RADIOSHACK-CUE-CAT-BARCODE-SCANNER-PS2-INTERFACE_W0QQitemZ250375591290
hi
Where can i find that nokia display with joystick for sale in europe?
I’ve been searching and i only find it in sparkfun electronics.
I’ve also have a lot of old mobile phones, maybe i could get a controler and make it myself, is this possible? and could somebody give a hint with this?
I need to double-check but I think it does not touch digital I/O pins 0 through 7. It’s got a header soldered in, but no traces from those pins. Unsolder and put in some tall-stacking female headers instead.
if you’re looking for a cheap ps2 scanner, look for an old radioshack cue cat. they dont make them anymore, but sometimes you can find them for cheap i.e. less than 5 dollars.
Thanks for your help people.
I’m going to order the display from nuelectronics. Halley, good tip
About the scanner, since i’m going to use ps2, first i’m going to make all the tests with a keyboard, and after if i manage to create some kind of csv file with the keyboard input, and display some information. i will search for the barcode reader.
