changing RFID values via VB form

Is there a way to change the RFID values in my arduino via VB made form where the user will plug in data and it will update the arduino via USB?

I'm not quite sure what you are asking.

But, you can communicate from a VB program with Arduino.

So if you want to send some kind of data from a VB program to Arduino it is possible. Just remember that the USB port on Arduino is really a serial port, so in the VB program you must send data out the correct serial (COM) port.

How you do that depends on what version of VB ( VB 6.0 or earlier or you are working with.

Turbo, if you are reading DEC numbers from the RFID reader (eg something like 31460678) and want to convert this to a site number and card ID, check out this post:
