I bought all the parts in the video description in the same way. Could you provide me the code for reference? Please understand that grammar can be strange because it is a translator.
hi bro..kindly tell me...there in this video u also use electronic module bcz i am working on this but i not abel to fina bar code scanner and electronic module..plz guide me...thanks...
Hello Sir, can u please tell me where did u buy that barcode reader. plz post a link if you have have bought it online. and majorly i need the information whether it is a UART output barcode reader ? please reply for my questions i am in real emergency & i urgently need it for my project work. plz help me.
I bought mine through a local reseller but here is the product direct from the manufacturer that I bought www.dfrobot.com/product-1135.html?tracking=58b60e381054a
Thanks! I only have a scanner without the blue board underneath. Is it just to add the button and buzzer? (Then I could just make my own) Or is there more to it?
No, there's a lot more to it. They generally all work the same. If you are unsure, connect an oscilloscope and see what signals you get out of it when it scans a barcode.
Sir we are working on projects in which using this sensor.. it will be a great help by you if send code.. how u interface with Arduino mega? Please sir waiting for your reply
I didn't use a RS232 to TTL converter, just opened a serial port and connected directly and told it to spit out to the log window then created a program based on that data.
Sir can you please send code of this barcode module. we are using lv4 barcode module and we are having trouble in assigning values. urgent help is required.
sure, just send me the serial UART values you get from your scanner for each number and I can write you the program. Without them it's useless as it will be different for every single scanner. If you don't know what I'm talking about look at the UART tutorial on the Arduino website and and/or use your oscilloscope to help you.
Hi, whenever a barcode is scanned by the scanner it spits out the data over the UART. Just configure one of your hardware serial ports on your mega to read the data. Baud rate should be set to 9600 which is the default for the scanner.
Hi Thank you so much for your reply. I am sorry, but I am very new to this so apologies in advance if my questions seems silly. When you say configure your hardware serial port, would that suggest a change to be made to my code? my usb shield library (.h file) or a hardware change?
Have a look at this tutorial www.arduino.cc/en/Tutorial/MultiSerialMega, I am using an RS232 scanner powered externally using a test bench type power supply set at 5V and less than 500mA available current which is plenty. Change byte to int in the tutorial, as you gets numbers from this scanner over serial. You computer serial monitor should show numbers coming from the scanner when it scan something. NOTE: They are not going to be the barcode numbers, but serial level numbers from 0-255. You need to figure out what each numbers serial level is and convert it with something like an if or case statement.
my friend can i convert the code to number (price) in Arduino ?
and do total for all price of product ?

Hi ! Do you remember how you configured the scanner ?
because when I try to read a barcode, the only thing I see is "?????"

Sir, can you send me code so i can figure out where i need to work on my programming?

Hi,
What is the program you use on arduino ?
How do we get the product prices ?
build a database
Do you have a sketch of the wiring and code? Mine does not seem to turn on at all :(
+MuckYu Double check the data sheet, I am using a DF-DFR0314 scanner. Use the barrel plug to supply 5V to the scanner.

Open a serial connection to the scanner and monitor the incoming characters.
Ola amigo, muito bom. Poderia mim passar o codigo? Desde ja agradeço
can i get the code please..
im using rs232 barcode scanner and using rs232 to ttl convertr
I didn't use a RS232 to TTL converter, just opened a serial port and connected directly and told it to spit out to the log window then created a program based on that data.
show me your programme please !
Sir can you please send code of this barcode module. we are using lv4 barcode module and we are having trouble in assigning values. urgent help is required.
I'm facing the same issue. do let me know if it resolves
why don't you go for LV3000
hello, can u provide barcode scanner type please?

Hi, Would you be able to share your code please? I need help with setting up my barcode scanner with my arduino mega
much appreciated!! :)

also, may I ask what external power supply you are using?
