Connect a USB cable to the pins on Arduino

I want to connect a USB cable to the pins on an Arduino to send text strings, like a gun that reads barcodes. Where do I connect? Do I need any special libraries? And as hardware, is the board and cable adapted to the pin connection sufficient?

Welcome to the forum

Which Arduino board are you using ?

I am using Arduino nano, but I can change boards if needed!

Then why not use the USB port on the board and print the text to it ?

Alternatively create a second soft serial port and use an external TTT to USB module and print to that

Because I need that port to power the board, the port where it sends the string does not have enough current to keep the board and the sensors connected.

I haven't found much on this TTT extension, can you send me some links so I can investigate further. Thanks for the support!

Connecting something that has a USB connector can not be used on an Arduino like you are thinking it can.

USB is a complex protocol and is not a simple serial stream of data. At best you need a USB host shield to attach to your Arduino.

Thank you!!

Good idea, I've been using this adapter "FTDI USB to TTL Serial Converter Adapter FT232RL Module" to program an ESP32-CAM and it work's just fine.
