Barcode Scanner with Raspberry PI

[@adrianhatesjazz]

Thanks for your summary of this great project. For true 'fullscreen' use window.attributes("-fullscreen", True) or window.attributes("-fullscreen", False) to exit fullscreen. You can bind that to (for example) F11 via window.bind_all("", func=toggle_fullscreen) and toggle back and forth in def toggle_fullscreen().

Lovely useful video and project. Totally love it. The way you use function part instead of class for now is actually making it easier for beginning programmers to understand the concept better. Thanks man.

The demonstration of this concept was super awesome.....keep uploading video's..Thankyou

I have to point out my great appreciation for the commenting in this Python code. So many "how to" coding resources online have terrible to no commenting, which makes it pretty difficult to figure out how to adapt code to our own applications.

@7:28 i think you need teamviewer instead, Remote desktop connection from my experience is like having two monitors where in each of them does not know what the other is doing, or simply the screen is not shared, on your raspberry pi the barcode is trying to push data, however since your using a remote desktop you won't see what the main unit is doing.

amazing project ! helped me a lot :) Thank you

Good Idea! It's a great proyect. 👏👏👏

Nice project!!! Cool and very simple.

[@seanmcdonald656]

Fantastic project. I really want to try building it.

[@moek8924]

Well done, could have done the timer in the code without the timer hardware.

Hi sir so I can Use any kind of scanner? Im an Electronics Engineering student and our project is to create a rpi based barcode scanner. And we dont know what kind of scanner we will use.

Did you happen to print the barcodes a special way? I've been using my barcode scanner to read the barcodes on the back of general products from a supermarket but when I print one out it won't scan it. I've tried changing the size of it, the type of barcode and the quality of the print.

[@TonyPDavis]

I didn’t have a problem with the size of the bar code, it seemed to work with a whole range of sizes but I found that “Code-39 Full ASCII” worked best. One thing that you should check is that the barcode scanner is sending out a “carriage return” after scanning the code. If does not do this it will definitely cause you a problem. I had to configure my scanner to do this because by default it was disabled.

[@MarshMello00]

@@TonyPDavis I got back round to this little project today and I managed to fix it by printing my bar codes on glossy paper instead of normal paper. Thanks for the response.

Watching in 2025 , Thanks for the code

good job I like you.

Hello Davis, Very good Explanation I enjoy your complete solution. I have a question about scanners, how do you read the scanner code, did you base your solution on this code? www.raspberrypi.org/forums/viewtopic.php?f=45&t=55100 I have had problems reading the scanner code as a serial, on the rasp.
