USB Barcode Scanner (Raspberry Pi)

[@shawnkhoo1949]

Super great video. The only video that shows how to obtain info from the barcode scanner connected to the RPi. This gave me a kickstart on my project. Thanks!

[@alientoken4517]

Thanks for the comment. Exactly what i was looking for!

[@PiddlerInTheRoot]

Just a note, this approach is deprecated. Check out: kzbin.info/www/bejne/eHbWhqOlr9t9ebc for a more up-to-date tutorial

[@ashittandon9301]

Dude, u are a life saver. Was going bonkers figuring out how to read the scanner on the pi. This worked

[@trashcan4065]

Very cool, thanks for sharing! I am thinking about cataloging the stuff in my pantry to aleviate the chaos in there just a little bit and your solution seems pretty well fit for that job :D

[@willfreeman9820]

That first config option you changed was for enabling the login shell over serial. I don't think this step is relevant to using the scanner.

[@liquidsonly]

Yes this enables serial on two GPIO header pins (14 and15?). Not needed for this at all.

[@innokentiyromanchenko1450]

does it catch only input from scanner, not from other HID devices?

[@maxdondada]

Excellent video! You have gained a new subscriber. Question: Why are you wearing gloves? Are you a magician? Are you a chauffeur? Did you steal the Barcode scanner? Did you just bury a body?

[@vishalgaurav4411]

Maybe hand is burned ?

[@evilchaperone]

Are you a magician? Bahahaha.. You win my day.

i want to change the barcode scanner mode to continuous mode. BUT NOT a regular continuous mode. i want it always decode and read the barcode just as written in spec. i mean yes there is auto-induction conf, but that's not fast enough, i want it always read 200 times/second A.K.A 200Hz. is it possible???? i'm aware that there is other "High Speed" barcode scanner that says 2500 times/second. but the max auto-induction time is 0.3 second. not fast enough... did i miss any configuration or sometin'???

[@NANOPLAYER]

when i press button of bar code scanner for scanning a bar code using ie 11 or goolge chrome its press (ctrl +j) and open downloads window instead of just scann and press enter only. i have ionic sr30 , is there any option to disable this command (control +j )

[@stevedeforest2813]

I have everything working, but when I send the query to upcdatabase, it always comes back with invalid "api_key". it shows it as null in the response. I have double checked my api_key, added an "api-key=" like I saw on their site, checked for extra space characters but it never works. The response does in include the correct barcode that I send. I print out the url before it is sent with 'get' so that I can verify it looks ok. Thanks (great video on getting this all to work).

[@stevedeforest2813]

never mind, figured it out. thanks.

[@stevedeforest2813]

jic someone else gets to this point "url = "api.upcdatabase.org/product/%s"% (upc + "?"+ "apikey=" + api_key)"

[@karlventer8873]

Hi Can you create and print your own barcodes for your own database -- I e read that number at the start eg 072............................. and say that is coffee?

[@cmansfield81]

How would you export this data to a csv?

[@gagarmel4358]

Great video Piddler, do you have any pointers if i'm looking to open a specific document with a specific barcode? Have a 7inch display-c connected to the rsp :)

[@PiddlerInTheRoot]

Thanks, if I understand your workflow correctly it should be fairly straightforward. Get barcode string, append file type to the end, open the file then read the contents, and print to the screen.

[@gagarmel4358]

@@PiddlerInTheRoot Probably not for me, but you learn by doing :) Appreciate the feedback. Looking forward to more content.

[@stew9671]

Great, sadly i couldn't find an ean database thats free yet. (For German products) So i probably have to create my own. Database that accepts ean 8 / 13 and some variations. With user input as fallback as well as to add new data to it. Its just gonna be a pain in the ass to add most of the produkts. But its gonna be used for maniging the shopping in my flat share. As well as being a good practice for my job im learning rn.

[@liquidsonly]

I would not run this as root, or in fact run anything as root outside of doing admin on the system. Add the user to plugdev group then add and add-edit /etc/udev/rules.d/99-scanner.rules so that the plugged in scanner belongs to plugdev group. Now a regular user in the plugdev group can access the scanner. There are many tutorials as to how to do both these things on the web.

[@mohitnama2158]

is this project possible on pico board ??

[@ethanbailey4637]

hey i have run this code but i get this { "status": "online", "message": "The UPC Database API is online, but this is not a valid endpoint. ", "endpoint": "spk035683P3", "time": 1572977289 } -------------------------

[@h7opolo]

would be better to make your own database. it's simply a text file. no login or internet service needed.

[@Azamat5991]

Hi, how to write if loops that will send digitalHigh to GPIO pins if the barcode of the item is the value that i'm looking for? For example, if(barcode='123123') {digitalWrite(pin, HIGH)} something like that

[@PiddlerInTheRoot]

Take a look at the sample code I provided on my website listed in the description. On line 86 I'm saving the value of the barcode scan... so you could pass that value into a function. The pseudo code you provided is essentially correct. Your function would do something like this: "if scan =='12345': GPIO.output(17,GPIO.HIGH)"

[@sanjking777]

hey man I think I'm doing something similar to you. Can you please show me the code you would use if you are looking for a specific barcode?

[@davis4740]

Can I open with the python IDE?

[@sanjking777]

Could you please tell me what I need to do?

[@PiddlerInTheRoot]

The site has changed a bit. Generate an API token and use that.

[@sanjking777]

I did that and run the url that is: api.upcdatabase.org/json/api_key/0793588523206 (Item_in_the_database) But it doesnt seem to work

[@sanjking777]

Can you please help me?

[@sanjking777]

Sorry for the inconvenience but I'm currently doing my senior design and I need to connect the barcode reader/scanner to the raspberry pi to scan a label on an autonomous robot. Can you please help me??

[@WolfVK-dh4jv]

is it possible to di it with wifi or bluetooth ?

[@PiddlerInTheRoot]

Pretty sure it's possible, working with bluetooth is a bit tricky on the raspberry pi though

[@geistesblitz9046]

Where is the program?

[@sanjking777]

hey man cant get the api key

[@sto2779]

6:00 - that barcode scanner is no good, it took like 10 seconds and 4 tries to get it scanned.

[@cyrinecharfeddine7950]

Are you working on Linux or Windows ?

[@BertClaes]

raspberry pi, so linux.

[@riseoftech4k332]

AWSOME VIDEO... good work.. i started to make arduino tutorials, if you want please check them out and tell me what you think ... thank you
