Hi everyone, I'm starting a project that will include a barcode scanner. Surfing the internet I found many guides but all of these use a wired scanner. If I use a wireless scanner with the adapter (included in the package) will it change anything to the code? Is better using a bluetooth scanner and a BT shield?
Thank you in advance
Which hardware interface is used by the scanner and adapter (serial, SPI...)?
Problems might arise with a serial adapter, using Rx/Tx, because most Arduinos have only one hardware USART, which also is used in downloading sketches. In this case the SoftwareSerial library may be required.
I'm going to use the SoftwareSerial library anyway for a Bluetooth connection between the arduino and the pc. The scanner and the adapter have usb ports and they work like a keyboard on a pc when you scan something. So, I'm going to use the usb shield on arduino and going to read the text from the scanner through the adapter. I think it should work. Am I wrong?
