How Can I use my Barcode scanner to my Arduino? with Serial RS232

Projects General Guidance

Hi I'm new to arduino projects and I want to use a barcode scanner to my arduino project but I read that RS232 Serial are not compatible with TTL which the arduino uses. is my understanding correct that I can use a RS232 to TTL Converter to connect my barcode scanner to my arduino?
I'm planning on using this barcode scanner. Thank you for reading.

if the device output is RS232 you will require a RS232 shield to interface it to an Arduino - have look on EBAY for Arduino RS232 shield

Yes.

Hopefully not.

Hopefully you would use a Nano rather than the inconvenient UNO, and a simple RS232 interface module.

Yep. ttl/rs232 level shifter is the order of the day. Nice unit. What'cha making?

Thanks for showing me this I'll try to use this for my project thank you for replying.

I'm trying to make a parcel receiver using arduino with a barcode scanner where delivery man can use a machine (like a locker system) to deposit your parcel when no one is present to receive the parcel in person. the barcode scanner is for the delivery man to verify the parcels tracking ID before it can be deposit in the machine. thanks for replying btw.

Hi,
i'm looking to do something similar.
Could you please share how did you end un using the MAX3232. Thanks
